ISC Twin Leg Tether

Designed for optimal Rope Wrench performance, the ISC Twin Leg Tether delivers improved alignment, control and efficiency in SRT climbing systems. Its twin-leg configuration allows the tether to straddle a cranked hitch-minding pulley, creating a more balanced and responsive setup.

A rubber grommet at the top attachment helps reduce excessive sit-back, keeping the Rope Wrench correctly positioned for minimal friction during ascent while ensuring fast engagement on descent.

Constructed from 100% Technora cord, this tether offers exceptional strength, rigidity and abrasion resistance—built to perform in demanding arborist environments.
