Handled Ascenders

Handled ascenders improve ease of climbing by giving you a large handle to hold and allowing the device to get a purchase on the rope rather than having to grip with your hand. This reduces the strength needed to grip the rope, and lets you have more endurance left to climb. Ascenders move freely up the rope but the cam is engaged when weighted, making these devices useful for ascent only. There are single and double handled ascenders available, and even double-cammed ascenders for use on doubled rope. The most popular hand ascenders are compact, single-handled ascenders which are easily stowed once you've reached your desired height and are ready to work the tree or descend.

Double-handed ascenders can be be used in the same manner as single-handled ascenders, but also offer advanced uses on doubled line. Either way, with two handles the user is afforded a more comfortable, powerful grip.

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