The safety carabiner with the locking clip.
The DMM Belay Master 2 provides added safety. The patented locking clip can only be closed when the screw lock is properly closed. This means you won't forget to secure your carabiners. The latch also prevents the carabiners from twisting and thus cross-loading. As well as being easy to use, it is very robust and impresses with its top quality. Perfect for belaying and abseiling.
