The DMM Small Impact Block is small by name, small by nature (relatively speaking) yet still big in strength. With a massive Minimum Breaking Strength (MBS) of 200kN and a Working Load Limit (WLL) of 40kN, it is incredibly strong, yet can almost be carried around on a harness. Rounded edges to cheek-plates maintain low rope abrasion when rope is fed ‘unfair’. Upper sheave opens via a threaded locking axle for added security. Thrust surfaces increase tolerance to external loading of spindle and anchor pin. Lightweight attachment sling facilitates hauling of block, sling and rope to the climber and helps with handling, in tree stowage and workshop storage. Direct connection to cordage, the anchor slings helps ensure correct neighbour component compatibility. High efficiency oilite bushings to reduce friction.
