ISC Large Cast Pulley- for 19 mm (3/4 in) Rope

Description

ISC Rigging Blocks have color-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.
