The large version is manufactured using cast aluminium. These blocks are rope friendly, durable and extremely robust. These features combined give maximum security and strength whe n 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 Aluminium and the special manufacturing process allows these pulleys to offer a highly impressive strength to weight ratio.
