For a tree climbing rope with minimum elongation and high breaking strength, we offer our 7/16" Wizard Line, available with or without an eye (sewn or hand-spliced), as you require. It's pre-conditioned for a smooth feeling, and provides great control on descents and easy retrieval.
We actually answer our phone (and emails). Try us! Call 705-437-1470 or contact us online. We will be happy to help you with any stock or custom rope, line, cord or lace needs you have.
