The Worx 6-pack grass trimmer/edger spool line is made from a patented copolymer nylon resin and synthetic material designed with an oval aerodynamic shape known as Double Helix DNALINE2. This patented design increases edging life up to 25% compared to normal use conditions. This patented resin line is softer allowing for the line to stretch and cushion on impact with hard surfaces. It has over 100 lbs. of tinsel strength compared to old lines that only offer 68 lbs. of strength. DNA2 trimmer line is durable and flexible for longer life. Simply pop off the spool cap cover and install the pre-wound 10 ft. of spool and line onto the trimmer without tools.
