There is an ISC Rigging Block for all applications.
The Compact Rigging Block is a lightweight pulley, which fits in the palm of the hand. At approximately half the size of the small cast pulley, the compact pulley offers a highly impressive strength to weight ratio.
The small and medium versions, now manufactured using Hot Forged Technology, combined with high quality materials and components. These blocks are rope friendly, durable and extremely robust. These features combined give maximum security and strength, when the block is rigged as part of an impact system.
The large rigging block has the size and strength to suit the largest of arborist rigging requirements.
Apart from the aesthetically pleasing curves, the ISC rigging pullies are 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.
