ISC Spring Locking Small 3/4" Rigging Block

The ISC RP052 is a 3/4" arborist rigging pulley with hot forged side frames, combined with high quality materials and components. The RP052 is rope friendly, durable and extremely robust arborist block. These features combined give maximum security and strength, when the block is rigged as part of an impact system.

Apart from the aesthetically pleasing curves, the ISC impact pulley is designed to work (together with textiles) to absorb the huge forces which are created by the harsh dynamics of heavy arborist work. The side plates are produced using the best quality hot forged aluminum and the special manufacturing process allows these pulleys to offer a highly impressive strength to weight ratio.
