At approximately half the size of the standard small rigging block and weighing in at only 490g (1 lb.), the new compact rigging block offers a highly impressive strength to weight ratio, with an 85kN (19,000 lbs.) MBS and WLL of 17kN (3800 lbs). The pulley plates are made from hot forged aluminum and it is this manufacturing process which allows such a compact pulley to boast such great strength and dynamic load bearing capacity. The pulley is fitted with a spring-lock closure mechanism which allows direct connection to rigging slings. This mini-block is designed for 1/2" (13mm) rope and the top sheave will accept 5/8" rope which can be used to attach a falsecrotch lanyard or whoopie sling. Show more
