Mammut Assist Belay Resistor, from the brand Mammut, is an assisted braking device that allows you to climb with someone lighter or heavier than you.
Lightweight, it attaches to the first quickdraw and increases rope friction, allowing a lighter belayer to stop the fall of a heavier lead climber.
Thanks to the patented cam construction, only a fall or lowering activates the resistance, and the rope is never completely locked.
This device therefore allows for smoother handling and softens falls gently, which facilitates dynamic belaying.
Dare to venture onto new routes with complete confidence with the Mammut Assist Belay Resistor.
