A ANLEOLIFE .155" Square Heavy-Duty Trimmer Line 3 lb Spool — Nylon 66, Commercial Strength

Anleolife .155" commercial square heavy-duty trimmer line is a 3 lb (280 ft) high-strength nylon 66 copolymer cord designed to tackle thick brush, briars, brambles, and heavy grasses with fewer breakages.

This high-capacity spool supplies a heavy-gauge, multi-sided square profile line that delivers aggressive cutting edges and extended life for demanding trimming tasks. Built from a nylon 66 copolymer with plasticized additives, the line resists impact and abrasion during repeated heavy use. It’s intended for professional or serious homeowner use in trimmer heads rated for .155" line diameter and pairs with high-capacity gas and battery trimmers.

How does the square profile help cut dense brush?

The square cross-section creates multiple sharp edges that bite into thick vegetation more effectively than round line. That geometry concentrates force along the sides so the line slices through briars, brambles, and heavy weeds with less rolling and tearing.

• Multi-sided edges improve slicing on tough stems
• Reduced rolling reduces missed cuts and rework
• Better performance on woody or fibrous plants than round line

Will this spool work with my commercial trimmer head?

Use the spool only with trimmer heads and spool systems rated for .155" line diameter. It fits many high-output gas and high-capacity cordless heads from mainstream manufacturers, but it’s not intended for light-duty consumer heads that can jam or overheat with thicker cord.

• Compatible with heads rated for .155" line (check your head’s spec)
• Works with many Husqvarna, Echo, Stihl, EGO, Oregon, Milwaukee, DeWalt-compatible heads
• Not recommended for light-duty or small-capacity consumer spool housings

How durable is the nylon 66 copolymer construction?

The nylon 66 copolymer base provides good tensile strength, while plasticizers add impact resistance to reduce breakage when contacting stones, fence posts, or thick brush. This combination yields longer run times between re-strings under heavy loading compared with standard round line.

• Nylon 66 copolymer for higher heat and abrasion resistance
• Plasticized formulation improves impact strength and flexibility
• Designed for frequent, high-load trimming sessions

How much line do I get and how is it useful on big jobs?

The spool contains about 280 feet (3 lb) of .155" line, giving you substantial runtime before needing to refill. That length suits extended commercial or property-maintenance work and reduces downtime for reloading compared with smaller spools.

• 280 ft of heavy-gauge line per spool—fewer reloads on large sites
• 3 lb spool weight provides consistent feed in compatible high-capacity heads
• Built-in cutter compatibility helps pull, cut, and reload in many heads

Who is this for: This spool is aimed at landscapers, groundskeepers, and homeowners with demanding trimming needs who use high-output trimmers or commercial heavy-duty trimmer heads. Choose this Anleolife .155" square line if you regularly cut dense brush, thick grass, or brambles and require a robust, long-running cord that reduces breakage and reload frequency. Always verify your trimmer head supports .155" line before installation.
