ISC 1/2" Falsecrotch Block

The RP050 from ISC is a hot-forged aluminum block made from aluminum alloy designed to work with your ropes to absorb the huge forces associated with arborist rigging. It is incredibly light and but strong. The quick-twist spring lock retains the upper sheave so there are never loose parts. The side plates are broad enough to protect lines during use and are anodized for a durable finish.
