The 11 Best Weed Eater String Replacements

The BLACK+DECKER AF1003ZP replacement spool pack provides factory-wound 0.065-inch trimmer line tailored specifically for the brand's auto-feed trimmers. It is designed for suburban homeowners who want a fast, reliable solution when maintaining clean lawn borders without the hassle of manual line winding.

A primary strength of these genuine spools is the uniform factory winding, which minimizes spool jams and mid-trim line snaps. Working via centrifugal force, the system automatically advances fresh line as needed while spinning, completely bypassing the need to bump the head or manually pull line.

However, the slender 0.065-inch profile is engineered strictly for light lawn grass and sidewalk edging. Homeowners attempting to cut through heavy brambles, thick stalks, or rough masonry will find that this thinner gauge line frays and snaps relatively quickly.

Bottom line: For routine yard maintenance on compatible BLACK+DECKER trimmers, this three-pack delivers seamless drop-in convenience and dependable automatic line feeding.

• Brand: BLACK+DECKER
• Line Diameter: 0.065 inches
• Line Length: 30 feet per spool
• Pack Size: 3 replacement spools
• Feed Mechanism: Centrifugal auto-feed (AFS)
• Model Number: AF1003ZP
• Warranty: 2-year limited warranty

These replacement spools are engineered to fit a wide range of BLACK+DECKER corded and cordless string trimmers. Compatible model families include BESTA51, BESTA512, BEASE62, CST1, CST12, CST2, GH4, GH5, GH6, GH9, LST12, LST136, LST14, LST21, LST22, LST3, LST4, LST42, LST522, LST118, LSTE522, LSTE523, LSTE525, NST118, NST124, NST181, NST218, ST7, ST72, ST77, ST86, and ST9.

Installation is tool-free and takes under a minute. Simply unclip the trimmer head cap, take out the depleted spool, clean out any collected grass clippings, feed the new string through the eyelet, and press the spool firmly into the housing until the cap snaps back into place.

How does the automatic feed mechanism work?
The system relies on centrifugal force while the motor runs. When the trimmer line wears down and shortens, the altered rotational balance automatically advances a fresh segment of line without requiring manual bumping.

Can empty spools be manually reloaded?
Yes, the empty plastic spools can be manually reloaded with bulk 0.065-inch line, though factory-wound replacements provide significantly better feed consistency and fewer internal jams.

Is this line suitable for thick weeds?
The 0.065-inch diameter is formulated for everyday turf, edging along fences, and soft lawn weeds. Thicker brush and woody stems will break the line quickly.

The EVENTRONIC AF-100 replacement spool set is made for homeowners who depend on Black+Decker string trimmers to keep their lawn edges neat. By providing pre-wound spools filled with 0.065-inch nylon line, this bundle eliminates the tedious chore of measuring and hand-winding replacement string.

The core strength of this set lies in its upgraded nylon polyamide material, which provides over 100 pounds of tensile strength. The flexible line yields on impact with hard surfaces like curbs and fences, reducing line breakage and maximizing cutting efficiency. Each spool works with the tool's centrifugal force system to advance fresh line automatically during operation.

While this trimmer line is well-suited for everyday turf trimming and edging, its 0.065-inch profile is not built for clearing overgrown brambles or thick brush. Landscapers tackling heavy-duty overgrowth will need a commercial trimmer designed for thicker string, and owners of dual-line trimmers should look elsewhere.

Bottom line: This pre-wound spool kit offers a dependable, low-maintenance way to keep Black+Decker grass trimmers running smoothly through routine lawn care seasons.

• Line Diameter: 0.065 inches
• Total Line Length: 240 feet
• Material: Nylon polyamide (tensile strength over 100 lbs)
• Item Weight: 12.3 ounces
• Package Dimensions: 10.98 x 5.98 x 1.73 inches
• Feed Mechanism: Centrifugal automatic feed spool
• Compatible Spool Models: AF-100, AF-100-3ZP, AF-100-BKP, AF-100-2
• Included Hardware: 8 replacement spools, 2 RC-100-P spool caps, 2 springs

This replacement pack is engineered for Black+Decker trimmers that use the AF-100 spool pattern. Compatible trimmer series include corded and cordless models such as the GH400, GH500, GH600, GH900, ST7000, ST7700, CST1000, CST2000, LST136, LST220, LST300, LST400, LSTE523, BESTA510, and BESTE620.

To install, remove the old spool cap, extract the empty spool, and check the condition of the retention spring. Feed the line tip through the trimmer head eyelet, seat the new spool firmly into the hub, and snap the replacement cap back into place until it clicks securely.

• 8 Pre-wound trimmer line spools (0.065-inch diameter, 240 feet total length)
• 2 Replacement RC-100-P trimmer spool cap covers
• 2 Replacement spool retention springs

The Eventronic 15-pack trimmer spool set is built to keep Worx cordless weed eaters running without interruption. It is specifically designed for homeowners and lawn care enthusiasts who want quick line changes during weekly mowing, edging, and trimming routines.

Each spool is pre-wound with high-strength nylon line engineered to deliver improved wear resistance and prevent snapping along curbs and fences. The line profile minimizes drag at high rotational speeds, allowing the trimmer motor to maintain efficiency while operating smoothly with the automatic feed system.

While this set provides ample line for common lawn maintenance, it is made for light to moderate grass and weeds. Homeowners needing to clear dense brush, saplings, or thick briars will find this standard-diameter line too light for heavy clearing jobs.

Bottom line: This convenient replacement set provides reliable cutting power, essential spare caps, and ready-to-load spools that take the hassle out of maintaining your Worx weed eater.

• Brand: EVENTRONIC
• Item Weight: 1 pound
• Package Dimensions: 7.36 x 5.63 x 1.46 inches
• Line Material: High-strength nylon
• Spool Count: 12 pre-wound spools
• Cap Count: 3 replacement caps
• Part Reference: WA0010
• Feed Type: Automatic feed system compatible

This replacement pack is designed to fit a wide selection of Worx cordless string trimmers using the WA0010 spool standard. Compatible trimmer models include WG122, WG150, WG151, WG151.5, WG152, WG153, WG154, WG155, WG155.5, WG156, WG157, WG160, WG160.1, WG160.2, WG160.3, WG160.4, WG162, WG163, WG165, WG166, WG166.1, WG167, WG170, WG170.1, WG170.2, WG170.3, WG175, WG175.1, and WG180.

Installation requires no extra tools. Simply turn off your trimmer, press the release tabs on the trimmer head to remove the existing cap, lift out the empty spool, thread the new line through the eyelet, and snap the spool and cap cover back into position.

• 12 x Pre-wound WA0010 nylon trimmer line spools
• 3 x Trimmer head replacement spool caps

The EVENTRONIC AF-100 trimmer line refill kit is designed for homeowners who rely on Black+Decker string trimmers for regular lawn maintenance. With pre-wound spools and bundled replacement hardware, it saves time and eliminates the frustration of winding bulk line by hand.

Each spool features 0.065-inch pliable nylon polyamide string with a tensile strength exceeding 100 pounds. This construction allows the line to bend and cushion upon hitting pavers or edging, while the centrifugal auto-feed system smoothly advances fresh string during normal operation.

Because this line is relatively thin, it is best suited for standard grass and light weeds rather than dense brush or heavy woody overgrowth. Trimmer owners requiring heavy-duty clearing line or running different trimmer brands should look for thicker, brand-specific options.

Bottom line: This complete multi-spool bundle delivers reliable cutting performance and hassle-free replacements for maintaining tidy lawn edges and light yard growth.

• Brand: Eventronic
• Model Number: AVL8
• Spool Compatibility: AF-100, AF-100-3ZP, AF-100-BKP, AF-100-2
• Line Diameter: 0.065 inches
• Total Line Length: 360 feet
• Material: Nylon polyamide
• Product Dimensions: 10.83 x 8.19 x 1.73 inches
• Item Weight: 0.035 ounces
• Package Contents: 12 replacement spools, 3 RC100P cap covers, 3 springs

This replacement kit matches the AF-100 spool standard and works with an extensive selection of Black+Decker corded and cordless trimmers. Supported series include GH models such as GH400 and GH900, ST series including ST7700 and ST9000, and CST cordless options like CST1000 and CST2000.

It also fits popular lithium-powered tools including the LST136, LST220, LST300, and LSTE525, as well as BESTA510 and BESTE620 units. Installation requires snapping out the old spool, clearing any debris, seating the spring, and locking the new spool down with the provided cap cover.

• 12 pre-wound 0.065-inch automatic feed trimmer line spools
• 360 total feet of nylon polyamide cutting string
• 3 replacement RC100P trimmer spool cap covers

The Viabrico 0.095-Inch Square String Trimmer Line provides a heavy-duty cutting solution designed for routine yard edging and stubborn overgrown vegetation. Formulated from high-density polyamide nylon, it suits both residential homeowners with expansive lawns and groundskeepers looking for durable bulk string.

The standout feature is its four-sided square profile, which offers sharper cutting edges compared to standard round nylon. This edge slices cleanly through dense weed stems instead of shredding grass tips, while the 110-pound tensile rating minimizes snapping when brushing against obstacles or wire fences.

However, this 0.095-inch diameter line will not fit compact battery trimmers engineered strictly for lighter 0.065-inch or 0.080-inch string. The crisp square corners can also round off faster when repeatedly scraping against rough concrete curbing or stone pavers.

Bottom line: If your trimmer accommodates a 0.095-inch line, this Viabrico square spool delivers impressive cutting power, low tangling, and strong snap resistance for demanding yard work.

• Line Diameter: 0.095 inches (2.4 mm)
• Profile Shape: Square
• Spool Length: 330 feet
• Material: Polyamide Nylon
• Color: Orange
• Tensile Strength: 110 pounds
• Item Weight: 1.63 pounds
• Product Dimensions: 5 x 3 x 6 inches
• Compatibility: Gas, electric, and cordless trimmers rated for 0.095-inch line

This trimmer line is engineered for broad compatibility across gas, corded electric, and cordless string trimmers designed to run 0.095-inch (2.4 mm) diameter string. Always check your trimmer manual to ensure your head accepts this gauge before winding.

To install, measure and cut your required length from the 330-foot bulk spool, then feed it into your manual or bump-feed spool head. Keeping even tension during manual winding helps prevent internal crossing and line binding during high-RPM operation.

Make sure your power tool is turned off, unplugged, or has its battery pack removed before handling the trimmer head. Forcing a heavy 0.095-inch line through smaller eyelets can cause feeding jams and unwanted motor drag.

• Wear protective safety goggles, ear protection, and sturdy closed-toe footwear whenever trimming dense brush.
• Store the nylon spool in a cool, dry area out of direct sunlight to prevent premature brittleness and cracking.
• If the line has been stored over a dry winter, soak the spool in clean water for 24 hours to restore nylon flexibility.
• Check that your trimmer deflector shield is securely attached to block high-speed debris kicked up by the line.
• Keep children, pets, and bystanders at a safe clearance of at least 50 feet while operating the trimmer.

The YWTESCH WA0010 replacement trimmer line 15-pack is designed for owners of Worx string trimmers who want a quick, hassle-free reload. Each spool arrives pre-wound, removing the tedious job of measuring and coiling bulk string by hand during routine yard work.

Featuring a 0.065-inch twisted aerodynamic line, these spools help minimize air resistance, motor drag, and trimmer vibration. The pliable polyamide nylon construction gives the string enough flexibility to stretch and cushion on contact with hard surfaces like stone walls or driveway curbs, yielding clean grass edges with less fraying.

While the line works efficiently on standard grass and light turf weeds, the 0.065-inch thickness will wear out quickly if used against dense, woody brush. Additionally, these spools are specifically molded for automatic feeding Worx trimmers and are not universal across other power equipment brands.

Bottom line: This 15-pack delivers dependable, drop-in cutting performance that saves Worx trimmer owners time and effort throughout the trimming season.

• Line Diameter: 0.065 inches
• Line Material: Polyamide nylon thread
• Spool Material: ABS
• Line Profile: Twisted aerodynamic shape
• Quantity: 15 pre-wound spools
• Spool Model: WA0010 (Item model WORX12)
• Item Weight: 9.1 ounces
• Package Dimensions: 7.32 x 5.63 x 1.46 inches

These replacement spools are engineered to replace Worx part number WA0010 across a broad selection of string trimmers. Compatible models include Worx WG122, WG150, WG151, WG151.5, WG152, WG153, WG154, WG155, WG155.5, WG156, and WG157.

They also fit the WG160 series (WG160 through WG160.4), WG162, WG163, WG165, WG166, WG166.1, WG167, the WG170 series (WG170 through WG170.3), WG175, WG175.1, and WG180.

Installation is tool-free: turn off the trimmer, pop off the trimmer head cap, take out the empty core, feed the new line end through the slot, and secure the cap back into place.

Always remove the battery pack or disconnect power before opening the cutting head or installing a new spool to prevent accidental startup during maintenance.

Wear eye protection, long pants, and sturdy footwear while operating your trimmer, as high-speed line can kick up loose rocks, twigs, and debris.

Store unused spools in a cool, dry area away from direct sunlight, as excessive heat exposure can dry out nylon line and make it brittle over time.

The YWTESCH 0.065-Inch String Trimmer Line Replacement kit is designed specifically for owners of Ryobi One+ cordless trimmers seeking an easy refill option. Each spool comes factory wound with 11 feet of line, allowing you to quickly swap out depleted cartridges and resume yard maintenance without stopping to wind bulk line.

A key strength of this set is the upgraded nylon polyamide material, which provides over 100 pounds of tensile strength to withstand high-speed spinning. The spool profile works cleanly with your trimmer automatic feeding system, helping prevent tangles and ensuring consistent line advancement along sidewalk borders and garden beds.

Because this line has a lightweight 0.065-inch diameter, it is best suited for standard lawn edging and common soft weeds. Homeowners dealing with overgrown pastures, dense woody stems, or rugged brambles will find that this thinner gauge wears down fast against rough surfaces.

Bottom line: This six-spool refill pack with an included replacement cap offers a convenient, dependable way to keep Ryobi One+ trimmers cutting cleanly through regular turf.

• Brand: YWTESCH
• Line Diameter: 0.065 inches
• Line Length: 11 feet per spool
• Material: Nylon polyamide
• Compatibility: Ryobi One+ 18V, 24V, and 40V trimmers
• Item Dimensions: 0.71 inches L x 2.2 inches W
• Item Weight: 6.4 ounces
• Total Pack Count: 7 pieces (6 spools, 1 cap)

This refill set is specifically designed for Ryobi One+ cordless string trimmers across the 18V, 24V, and 40V product lines. It matches the factory AC14RL3A spool specification for seamless installation.

Replacing an empty cartridge takes just seconds without requiring special tools. Remove the trimmer cap, take out the empty core, insert the new pre-wound spool with the line extended through the eyelet, and snap the cover back into place.

• 6 x Pre-wound 0.065-inch trimmer line spools (11 feet each)
• 1 x Replacement trimmer spool cap

The package contains seven individual items, supplying multiple full refills plus an extra cover to replace worn or damaged factory caps.

The EGO Power+ AL2420P twisted trimmer line pack is built specifically for yard owners who want quick, frustration-free maintenance on their 15-inch EGO string trimmers. Each pack contains five pre-measured 14-foot sections, eliminating the need to haul out shears or measuring tape during lawn care routines.

The twisted aerodynamic profile reduces wind resistance, which helps optimize battery efficiency on cordless string trimmers while yielding a crisp, level cut across stubborn weeds. At 0.095 inches in diameter, the commercial-grade nylon provides ample strength to trim around hardscapes and fence lines without snapping prematurely.

While the pre-measured strands save substantial setup time, high-volume landscapers may find pre-cut segments less economical than winding from a continuous bulk spool. Yards that require non-standard line lengths will also be limited by the fixed 14-foot sizing.

Bottom line: The EGO Power+ AL2420P pre-cut pack is a reliable, convenient choice for EGO trimmer owners who prioritize fast line loading and clean trimming performance over bulk spool savings.

• Brand: EGO Power+
• Model Number: AL2420P
• Line Diameter: 0.095 inches
• Cutting Width Compatibility: 15 inches
• Total Length: 70 feet (five 14-foot strands)
• Line Style: Twisted aerodynamic line
• Color: Orange
• Item Weight: 5.28 ounces

This genuine EGO replacement line is optimized for all EGO Power+ 15-inch string trimmers, including models equipped with Powerload technology. It is also fully compatible with the EGO multi-head system 15-inch string trimmer attachment (model STA1500).

The line can also be loaded into any universal or third-party string trimmer head designed to accept 0.095-inch diameter line. Because each strand is pre-cut to exactly 14 feet, loading requires no measuring: feed the strand directly through the head eyelets, center the line evenly, and wind.

Will this line work on non-EGO string trimmers?
Yes, this 0.095-inch line functions in any gas, corded, or cordless string trimmer head rated to accommodate 0.095-inch diameter line.

What is the advantage of a twisted line shape?
A twisted profile produces less aerodynamic drag and noise than traditional round line, improving cutting efficiency and helping conserve battery life on cordless trimmers.

How many total trimmer reloads are included?
The package comes with five individual 14-foot pre-cut lines, providing five full trimmer head reloads totaling 70 feet of line.

The EVENTRONIC 0.080-Inch Trimmer Line Spool set is designed for Ryobi cordless string trimmer owners looking to bypass the tedious hassle of manual line winding. Engineered to replace the Ryobi AC80RL3 spool, this package equips homeowners with ready-to-use cartridges that snap directly into compatible Ryobi ONE+ trimmer heads without fuss.

A standout benefit of these spools is the precision machine-wound copolymer nylon resin line. Factory winding significantly cuts down on jams and binding inside the housing, allowing Ryobi auto-feed mechanisms to advance line smoothly. In addition, the tough ABS spool foundation holds up well against high-speed trimmer rotation during typical lawn edging and grass trimming.

While ideal for standard yard maintenance, these spools are strictly designed for Ryobi equipment and will not seat properly in trimmers from other brands. Furthermore, each spool holds 11 feet of 0.080-inch line, meaning users trimming against hard fencing or tackling thick, woody weeds may wear through a spool quickly.

Bottom line: For owners of Ryobi 18V, 24V, and 40V trimmers who value quick push-and-click spool changes and reliable auto-feed performance, this 10-pack kit delivers dependable yard maintenance convenience.

• Line Diameter: 0.080 inches
• Line Length: 11 feet per spool
• Line Material: Copolymer nylon resin
• Spool Material: ABS plastic
• Compatibility: Ryobi ONE+ 18V, 24V, and 40V cordless trimmers (replaces AC80RL3)
• Package Quantity: 10 spools, 2 cap covers, 1 storage box
• Product Dimensions: 3.54 x 2.36 x 5 inches
• Item Weight: 12.3 ounces
• Manufacturer: Eventronic

• 10 x Eventronic 0.080-inch replacement trimmer line spools (11 ft each)
• 2 x Eventronic replacement trimmer spool cap covers
• 1 x Heavy-duty storage box for workshop organization

These replacement spools are engineered specifically for Ryobi ONE+ cordless string trimmers across 18V, 24V, and 40V platforms that use the AC80RL3 spool profile. To install, always disconnect the trimmer battery first for safety. Remove the old spool cap, extract the spent spool, and clean out any grass buildup inside the head housing.

Insert the fresh Eventronic spool by threading the 0.080-inch line through the eyelet and seating the spool firmly in the trimmer head. Snap either your original cap or one of the two included replacement covers over the assembly until it clicks securely. The precision machine winding ensures smooth line advancement with Ryobi auto-feed heads during standard trimming routines.

The Arnold Maxi-Edge .08-Inch Trimmer Line is a commercial-grade replacement line designed to tackle routine lawn maintenance and persistent yard weeds. Built with an edge profile engineered for durability, it is tailored for both homeowners and professional landscapers who want reliable cutting power without constantly reloading the head.

A standout feature is the 140-foot spool capacity, which supplies approximately seven refills for standard string trimmers. The package also includes an integrated cutting tool, allowing you to slice exact lengths without searching for snips or scissors in the middle of yard work. Its universal design works across most curved and straight shaft models.

While the .080-inch gauge effortlessly handles medium weeds and lawn borders, it is not built for heavy brush, briars, or thick woody stalks. Operators clearing overgrown fields or dense brambles will likely need a heavier line gauge to avoid premature wear along rough concrete and chain-link fences.

Bottom line: The Arnold Maxi-Edge .080-inch line provides a dependable balance of resilience and cutting efficiency for everyday yard edging and medium weed clearing.

• Brand: Arnold
• Model Number: WLM-H80
• Line Diameter: .080 inches
• Total Length: 140 feet (approximately 7 refills)
• Color: Green
• Compatibility: Fits most straight and curved shaft string trimmers
• Item Weight: 8 ounces
• Manufacturer Warranty: 3 months

The Arnold Maxi-Edge line features a universal design created to fit most gas, battery, and corded string trimmers. Whether your equipment utilizes a straight shaft for extended reach or a curved shaft for maneuverability in tight garden spots, this .080-inch line feeds cleanly through compatible trimmer heads.

Refilling your trimmer head is straightforward thanks to the included line cutting tool. You can measure out the required segment from the 140-foot spool and cut cleanly without hunting for utility knives. A single spool delivers around seven reloads depending on the spool capacity of your specific trimmer head.

Will this line fit my specific string trimmer?
Yes, this .080-inch trimmer line is engineered with a universal profile that works with most curved and straight shaft trimmers rated for .080-inch diameter line.

How many refills can I get from this spool?
The 140-foot spool yields approximately seven standard trimmer refills, giving you plenty of line for multiple lawn care sessions throughout the season.

Does this package come with a cutting blade?
Yes, the packaging includes a convenient cutting tool, enabling you to trim the line to your desired length immediately without needing extra tools.

The A ANLEOLIFE .095-inch twisted trimmer line is designed for homeowners, DIY yard enthusiasts, and landowners seeking reliable cutting power for general property maintenance. Wrapped in a 1-pound donut spool containing 393 feet of line, it provides a dependable replacement option for standard gas and electric string trimmers.

A standout feature is the 3-layer twisted spiral construction, which cuts through air with significantly less drag than traditional round line. This aerodynamic profile lowers operating noise, dampens handle vibration, and delivers clean, precise slicing across overgrown grass and dense border weeds.

Users with dense woody brush, rocky terrain, or heavy commercial clearing needs may find standard nylon lines wear down along hard barriers. Gardeners with lightweight electric or cordless weed eaters rated strictly for smaller line diameters should look for thinner options instead.

Bottom line: This 393-foot spool offers an effective balance of cutting efficiency, noise reduction, and spool capacity for regular grass trimming and lawn edging.

• Brand: A ANLEOLIFE
• Manufacturer Part Number: AN198
• Line Diameter: .095 inches
• Cutting Width: 0.24 inches
• Length: 393 feet
• Item Weight: 16 ounces (1 lb)
• Line Shape: 3-Layer Twisted Spiral
• Recommended Uses: Edging and Trimming
• Spool Dimensions: 6.5 inches L x 5.79 inches W

• Trimmer Compatibility: Fits weed eaters engineered to accept .095-inch gauge line.
• Brand Versatility: Works with compatible bump-feed and fixed heads from Echo, Stihl, Husqvarna, EGO, DeWalt, Milwaukee, and Oregon.
• Power Source Support: Suitable for both gas-powered and high-voltage electric or cordless trimmers.

• Verification: Always consult your trimmer user manual to confirm maximum line gauge before loading.

This line is suited for suburban homeowners and property owners who maintain small to medium-sized yards on a routine schedule. Its low-noise spiral shape is especially useful in residential neighborhoods where quieter power equipment operation is appreciated.

It is also a practical choice for DIY landscapers wanting a reliable, multi-season supply of line for general perimeter trimming, fence line maintenance, and lawn edging without constant trips to the store.
