The ISC RP255A1 Medium Pulley is a heavy duty arborist rigging block designed for demanding lowering and rigging systems. Its hot forged aluminum frame and interlocking axle design provide increased strength, while the low profile SafeLock mechanism allows quick opening with secure closure. The pulley accepts rope up to 3/4 inch, has a 60 kN working load limit, and a 300 kN minimum breaking strength.

The ISC 200 Series Pulleys are redesigned versions of the popular ISC arborist blocks with a new SafeLock mechanism and improved strength.
Using state-of-the-art stress analysis programs, the hot-forged aluminum frames are optimized for the forces arborists put on their blocks, and the unique axle and frame interlocking design means that these pulleys are up to 150% stronger than their predecessors. The Patent Pending SafeLock system is an updated version of the ISC SpringLock design that provides an extremely low profile along with the same quick opening action.
