Dynamic blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. The ball bearings are caged for further friction reduction. These features provide a superior load-carrying ability and longevity when compared to other bearing systems.\u003c\/p\u003e \u003cp\u003eUltra-Strap ?? Our patented Ultra-Strap is used in our 20, 30 \u0026amp; 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 rope friendly. The Ultra-Strap block is a great choice for dinghy jib or mainsheet systems.\u003c\/p\u003e \u003cp\u003eBecket ??
