POWERLINE USA Anchor Lines are available in various sizes, lengths and colors. Made of high strength polyester, POWERLINE USA Braided Anchor Lines offer greater durability compared to nylon anchor lines since Polyester doesn't lose strength when wet, stretches less than nylon and much more sunlight-resistant than nylon. Overall, Polyester anchor line simply offers better weathering characteristics than a nylon anchor line. In addition, Polyester lines offer less stretch than nylon; so mooring in an absolute stationary position is a great use for POWERLINE USA Braided Anchor Lines. POWERLINE USA also utilizes a braided design instead of multi-strand twisted design, which is less brutal on the hands. Made in the USA.
