Beranek Rope Walker Knee Ascender

Buy Beranek Knee Ascender


This neat little ascender system can be added onto one of our rope kits or used with your own setup. This kit was thought up by veteran climber Gerry Beranek. In the doubled rope technique, this system puts a footstrap on the Basic, which is in turn connected to the rope by a prusik on a custom bungee lanyard. This bungee advances the ascender as soon as you step up with your leg that is in the footstrap.

Will work in DdRT, SRT rope walkers, and racing rigs using a chest roller.

We started selling this kit in 2010 with an adjustable webbing loop (seen in the picture) which has been replaced by an adjustable Tenex foot stirrup.

Contents: Bungee, adjustable foot strap, Petzl Basic ascender, DMM XSRE carabiner.
