ISC RP055 Arborist Block

The release pin on most arborist rigging blocks is a threaded bolt which is screwed into a nut welded on the back of the plate. Once undone the plate slide free for easy rope entry. The ISC rigging block has a unique push-and-turn release mechanism - much quicker than threaded options. The top pulley, capable of taking up to 20 mm rope, stays attached to the pin and will not fall out when released. The side plates are caste in thick aluminum with a yellow epoxy polyester coating to enhance the life of the block. Stainless steel sheave and bushing pins. Mount to the tree with a Samson Loopie or a Samson Deadeye sling. Minimum Breaking Strength 150kN, Safety Factor 5:1 EN 12278
