Beranek Double Line Rope Walker


This neat little ascender system can be added on to any rope climbing system using 7/16” (11mm) ropes. This kit was thought by veteran climber Gerry Beranek.

This bungee advances the ascender as soon as you step up with your leg that is in the footstrap. Pretty keen.
