The largest of SMC’s Prusik Minding Pulleys (PMP), the 3″ Single PMP is designed to handle the heaviest loads and toughest situations. The large D ring attachment point can fit 3 large rescue carabiners and still allow them to move freely. The solid side plates and sealed bearings prevent snagging or unnecessary resistance to ensure efficiency and avoid misalignment. This pulley is excellent for everything from progress capture in hauling, highlining, or rescue scenarios.
