Duoline Round Trimmer Line, 4.0mm, 64m Spool

Quick Links:

Duoline Round Trimmer Line is ideal for professionals who need long-lasting, powerful tools to get the job done right. It quickly and easily cuts through low grass and grass-like weeds yet is durable enough to tackle sizable brush without breaking. This trimmer line is less likely to bond together in the trimmer head due to its weld-resistant outer layer. Duoline is compatible with most trimmer head systems including fixed-line, semi and automatic bump-feed heads. Additionally, it fits most gas, electric and battery-powered curved and straight shaft string trimmers. Check your string trimmer manual for recommendations and to ensure that larger lines will work with your trimmer.
