DMM Belay Master Clip

Twist-lock karabiner that incorporates an integral braking system for improving friction on descenders and belay devices. Works extremely well with the Grigri when using slimmer ropes such as the Beal Booster, which can normally be a struggle.

Don't deal with a cross loaded belay karabiner again! Specifically designed for belaying, the Gridlock isolates the belay loop of a harness behind the uniquely shaped internal gate, thus keeping the karabiner in the correct orientation. The Gridlock is simple, easy to use and effective.

Black Diamond's largest belay and rappel locker, the Black Diamond RockLock carabiner features a keylock nose, is Munter Hitch compatible and can be operated with one hand.

The DMM Belay Master 2  is a belay karabiner that has safety at its heart. The nylon crossgate means that you can be sure that the screwgate is locked properly if the crossgate is closed. It stops the chance of the screw undoing and retains the krab in the correct orientation so not weakening of the system can occur.
