.155" Orange Weed Eater String 100% Nylon Heavy-Duty Trimmer Cord 5lb, 1280' Length Round Weed Wacker String155 Trimmer Line for Garden & Grass Pruning

What It Is

This is a 5-pound spool of .155-inch diameter, round, 100% nylon trimmer line designed for heavy-duty trimming of thick grass, weeds, and light brush. It’s intended for gas, electric, and battery-powered string trimmers that accept a .155-inch line.

Fitment & Compatibility

Before buying, check your trimmer’s user manual or existing line for the correct diameter. This .155” line is thicker than standard .080” or .095” lines and may not fit trimmer heads designed for smaller diameters. It works best with heavy-duty trimmers (e.g., Echo, Stihl, Husqvarna, Ryobi) that have a line capacity of .155” or larger. It is aftermarket (not OEM), so verify your trimmer head’s maximum line diameter and whether it accepts round line (some heads require twisted or star-shaped line). Also, 1280 feet is a bulk spool—ensure your trimmer head can hold this line length (most heads hold 10-30 feet per load).

Key Things to Know

• Material and durability: 100% nylon, round profile provides good cutting power for thick grass and weeds, but round line is less aerodynamic than shaped lines, which may reduce efficiency at high RPMs.
• Installation difficulty: Easy to load into standard bump-feed or fixed-line heads, but the .155” thickness can be stiff to thread through small eyelets—use a line cutter or scissors to trim the end at an angle.
• Common gotchas: This line is heavy-duty, so it may be overkill for light residential trimmers (e.g., 20V cordless models) and could cause motor strain or reduced run time. Always match line diameter to your trimmer’s rated maximum to avoid damage.
• Bulk value: 5 lbs (1280 ft) is a large quantity—ideal for commercial use or frequent trimming, but may be excessive for small yards (consider a smaller spool if you trim less than 1 acre per season).

Should You Buy It

Buy this if you have a heavy-duty gas or high-end electric trimmer that accepts .155” line and you frequently tackle thick weeds, brambles, or overgrown grass. It’s a good value for heavy users, but skip it if your trimmer requires smaller line or if you only do light residential trimming—you’ll get better performance from a thinner, more flexible line.
