DMM ‘Helix Revolver Carabiner’

Product Overview

The Revolver’s pulley wheel reduces friction on ropes moving through the carabiner. Placed where the pitch changes direction, it reduces rope drag and makes upward movement easier.

The Revolver can be used in an improvised hauling system to help your second over a crux, haul kit bags, or rescue your partner from a crevasse. Where normal carabiners in these systems cause energy to be lost as friction, the Revolver’s pulley wheel makes hauling easier by converting more of your energy into movement.

A Revolver on your rack lets you reduce rope drag and make efficient mechanical advantage systems without the need for additional devices.

It’s also manufactured in Tactical colours it is suited to Military and Tactical climbing operations in both Mountain and Urban environments.

Keylock nose eliminates snagging

This carabiner’s nose slots into a groove in the gate, allowing it to achieve full strength without a gate notch. This creates a clean internal profile that won’t catch on gear, bolts or slings, giving easier clipping and removal from systems.

I-Beam construction for optimum strength to weight ratio 

I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process that allows the metal to be made into complex shapes that improve functionality.

Integrated pulley wheel for reducing friction 

The Revolver’s pulley wheel reduces friction and increases the efficiency of ropes running over it. This reduces rope drag on complex pitches, and rope wear when used as an anchor for top-roping. The Revolver can also be used to create a mechanical advantage in a lightweight personal hauling system, making it indispensable as part of a climber’s personal rescue kit. The pulley wheel is functional with loads up to 11kN.

Wire gate for maximum saving 

Wire gates are the lightest gate-type available and resist freezing shut in cold conditions. They help reduce rack weight and are ideal for trad, winter, and alpine climbing.
