Handled Ascenders

Ascenders move freely up the rope and engage the cam when weighted. Ergonomic handles give you a comfortable grib. This reduces the strength needed to grip the rope, and leaves you more endurance for the climb. Ascenders are useful on ascent only.

A hand ascender is a key component of any SRS rope walker system when used with a foot loop or knee ascender and foot ascender.
