Allen 20mm Dynamic Triple Block with Cleat And Becket

20mm Dynamic Triple Block With Small Allenite Cam Cleat and Becket. Our Dynamic range is generally the best choice for applications that require constant sheave movement.Bearings Ð 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.Ultra-Strap Ð Our patented Ultra-Strap is used in our 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.Becket - This triple block features a rope friendly becket (tieing off point).
