This single 30mm Dynamic Block with Fork has a fork attachment accessory that can attach securely with its threaded pin. The fork also has the ability to articulate slightly, aiding in rope alignment. Featuring our patented bearing system, this block uses twin rows of stainless-steel ball bearings on a stainless-steel rail, providing superior load-carrying ability and longevity compared to other bearing systems that use a plastic rail. Additionally, the block includes a large central rivet for a rope-friendly attachment and can be used as a tie-off point in a cascade system.
