ISC Spring Locking Compact 1/2" Rigging Block

At approximately half the size of the standard small rigging pulley and weighing in at only one pound, the ISC Compact 1/2 inch Rigging Block offers a highly impressive strength to weight ratio.

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 ISC Compact Rigging Pulley is fitted with a spring-lock closure mechanism.
