The DMM Revolver Locking Carabiner features an integrated pulley to reduce rope drag on a meandering rock pitch or reduce friction from your crevasse rescue system. Popular among search and rescue personal, this unique carabiner reduces the number of pulleys needed in complicated hauling and lowering systems. You can also use this DMM carabiner to take the sting out of that one mandatory piece of protection that's five feet outside the rope line.
