Still one of the most popular belay devices, The ABC Spring Plate locks off and feeds the rope easily without twisting or kinking. Keeping the rappel lines separate and untwisted allows you to pull your rope after a rappel with ease. This device from the Liberty Mountain house brand Advanced Base Camp (ABC) can be used for either belaying or rappelling with 9mm-11mm ropes.
