The next generation ISC Rigging Pulleys are up to 150% stronger than the equivalent ISC standard Rigging Pulley models. The new low-profile Springlock mechanism features a new 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.
