Grass Strimmer Line Wire Cord, 063" 680ft 1lb Heavy Duty Strimmer Wire, Nylon String Wire for Grass Strimmer Electric

What It Is

This is a 0.063-inch diameter, 680-foot spool of heavy-duty nylon strimmer line, designed for electric grass trimmers. It’s a universal aftermarket replacement for trimming grass and light weeds around lawns, edges, and flower beds.

Fitment & Compatibility

Before buying, verify your trimmer’s line diameter requirement—most electric trimmers accept 0.065-inch or smaller, but some gas models need thicker (e.g., 0.080” or 0.095”). This 0.063” line fits common electric brands like Black+Decker, Ryobi, Worx, Greenworks, and Toro, but always check your owner’s manual for the exact line size. It will not fit trimmers requiring 0.080” or larger. Also confirm your trimmer head’s line capacity—680 feet is a bulk spool, so you’ll need to cut it to length for manual or bump-feed heads. This is an aftermarket product, not OEM, so branding and packaging differ from what you’d get from the manufacturer.

Key Things to Know

• Diameter matters more than length: Using 0.063” in a trimmer designed for 0.080” can cause poor cutting and rapid wear; using it in a 0.065” head is fine.
• Nylon quality: This is standard round nylon line—good for light trimming, but it will wear faster in heavy weeds or against hard surfaces like concrete. Not as durable as square or serrated line.
• Installation is easy: Cut a 10–20 foot length (depending on your head), feed it in, and wind evenly. No special tools needed.
• Spool refill tip: If your trimmer uses pre-wound spools, you’ll need to wind this onto an empty spool yourself—it’s not a pre-loaded cartridge.

Should You Buy It

Buy this if you have an electric trimmer that uses 0.063” line and you want a cheap, bulk supply for routine lawn maintenance. It’s ideal for light to medium trimming on grass and soft weeds, but skip it if you need heavy-duty line for thick brush or if your trimmer requires a larger diameter.
