At approximately half the size of the standard small rigging pulley and weighing in at only 490g (1lb), the new Compact Rigging Pulley offers a highly impressive strength to weight ratio with an MBS of 19,000 lbf. (85 kN) and a WLL of 3,800 lbf. (17kN). The Pulley plates are made from hot forged Aluminium and it is this manufacturing process which allows such a compact pulley to boast such great strength and dynamic load bearing capacity. The Compact Rigging Pulley is fitted with a spring-lock closure mechanism.
