ISC Wales Rope Wrench 11-13mm

Rope Wrench (11-13mm)

A proven favourite in production climbing and competition settings, the ISC Rope Wrench is a simple, effective solution for enabling efficient SRT climbing systems.

By introducing an ‘S’ bend in the rope above the hitch, the Rope Wrench shares load between the device and hitch cord—allowing smooth operation on a single rope system without the need for traditional double rope setups. This results in improved efficiency, easier horizontal movement and reduced friction at redirects.

Available in multiple colour options, the Rope Wrench combines trusted performance with ISC’s renowned build quality.
