DMM REVOLVER WIREGATE

DMM Revolver Wiregate Carabiner

This is one of the landmark inventions in the journey of DMM Engineering. It was the first ever I-beam carabiner, spawning a new generation and since then DMM has been the much-copied King of the Krabs. Not only that, it is the only carabiner to have an in-built pulley for reducing rope-drag.
The benefits of this to the trad climber are not to be underestimated, and not just for the sort of ropemasters who occasionally find themselves hauling their own bodyweight in rope drag behind them. We know who we are.. It reduces friction by 30%, which makes life massively easier on long wandering trad pitches and can also help on placements where it is easy to lift the gear off, like a marginal spike thread. It is also very handy for hauling, and there is a screwgate version that is ideal for rescue situations.
It is worth being aware that a belayer relies more than you might imagine on the friction through the carabiners to hold a fall so if you are using one of these let them know or they may be catapulted to a land far far away, or just into the rock. Not pleasant!
