SOLD PER METER ''Cool' blue/green color. 24-strand Samson Vortex is a true 1/2" (12.7 mm) and is the lightest premium climbing line of its size available. Like its counterpart Velocity, but a little larger for easy handling, Vortex has excellent knot-holding ability, works well with hardware, and is great for footlocking. Compared to ropes of similar size, Vortex has 25–30% lower elongation when used at the same load. The low elasticity makes Samson Vortex the ideal rope for use with the Singing Tree Rope Wrench. The larger, 12.7mm diameter feels more re-assuring when working on a single line.
