The high load block features a stainless-steel sheave, providing faster speeds, higher loads, and lower friction compared to the acetal sheave. It can be used with both rope and wire in applications such as dinghies, windsurfing, and kitesurfing. The patented bearing system uses twin rows of stainless-steel ball bearings running on a stainless-steel rail for increased load-carrying capacity and durability. Additionally, the patented Ultra-Strap, unique in its coining process, ensures reliability, wear-resistance, and rope-friendliness. This block also includes a large central rivet for reduced weight and a rope-friendly attachment, making it ideal for use in a cascade system.
