DMM
Belay Master 2 $27 dmm’s new belay biner is updated with I-beam construction. But the best feature is the nylon clip that stops any twisting of the biner. Cross-loading is a hazard when belaying and biners with clips like this are much safer. A second advantage of the clip is that it lets the climber and belayer know that the system is locked and ready to use. It comes in at 93 g.
