Swivel Head A built-in swivel pin allows this block to swivel once attached. ideal for applications where the pulling forces may change direction. The swivel cannot be locked.
Bearings Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.
Fiddle The fiddle is a secondary smaller sheave which can be used to create an inline purchase system for a smaller lower loaded application. The fiddle features ball bearings.
Becket This block also features a removable clevis pin, for easy attachment or release of a spliced rope. It also allows this block to create a 4:1 purchase system.
