ISC Stainless 5/8" Flame Rigging Block

The Stainless Steel ISC RP056 5/8" Flame Rigging Pulley is probably the coolest arborist rigging block ever.  It features a screw locking knob and is manufactured using Hot Forged Technology, combined with high quality materials and components.  

ISC Rigging Blocks have color-coded side plates and pulley wheels, helping the user to easily identify the correct Block for the task. ISC has introduced a new fixed bollard dimension, which allows the user to fall in-line with rigging standard practice, whereby the Anchor Sling should be twice the Strength of the Working Line.
