The 20-foot WORX string trimmer and edger 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-percent compared to normal use conditions. This patented resin line is softer allowing for the line to stretch and cushion on impact with hard surfaces. The line is 0.08 x 20-feet and easily installs into the no-bump Worx trimmers.
