ISC Rope Wrench ZK-2



The ZK-2 Rope Wrench provides consistent friction for Single Rope Technique (SRT) climbing. It minimizes slack and has 1:1 efficiency. The ZK-2 allows simple redirects and works on multiple limbs.  

The rope wrench has rounded side plates and pins, minimizing rope wear. It’s fitted with a pulley wheel that supports the rope radius and minimizes rope compression. Use with a rigid tether (sold separately). Manufactured by ISC Wales.

Not to be used as primary life support.
