Hot-forged, extremely durable, rope-friendly, and extremely robust. ISC Rigging Blocks have colour-coded side cheeks and pulley wheels, helping the user to easily identify the correct block for the task. We have introduced a new fixed bollard dimension, which allows the user to fall in-line with rigging standard practice, whereby the Anchor/Topping Strop should be twice the strength of the working line.
