The small and medium versions are now manufactured using hot forging technology, combined with high-quality materials and components.
These blocks are rope-compatible, durable and extremely robust. These combined characteristics offer maximum safety and strength when the block is rigged as part of an impact system.
In addition to the aesthetically pleasing curves, the ISC shock pulley is designed to work (with textiles) to absorb the enormous forces created by the hard dynamics of heavy arborist work.
The side plates are produced using the highest quality hot-forged aluminium and the special manufacturing process allows these pulleys to offer a very impressive strength-to-weight ratio.
The steel cheeks are movable and can be closed using a quick-release fastening. The pulley can be attached directly to the sling (therefore without the use of a carabiner).
