ISC Compact Rigging Pulley
The ISC 200 Series Rigging Pulleys are up to 150% stronger than their predecessors. These are built to withstand even the toughest rigging jobs with ease. These blocks are made using hot forged high-strength aluminium frames with a unique axle/frame interlocking design using heat treated hardened stainless steel axles. This reduces the tendency to deform or flex under extreme loads. The low-profile Spring lock mechanism features a Safelock locking button to offer further security and ease of use. Simply push the Safelock button and turn the axle head 180° to the release position. The Safelock button can be depressed and the pin head rotated in a continuous one-handed action.
