Allen 20mm Articulating Double Dynamic Block

The 20mm Articulating Double Dynamic Block provides a one-of-a-kind solution for various applications such as dinghies, windsurfing, kitesurfing, and more. With low friction, fast rolling speeds, and a lightweight yet strong design, this block is ideal for smaller diameter lines. It features a patented bearing system with twin rows of stainless-steel ball bearings and a stainless-steel rail, providing superior load-carrying ability and longevity compared to other bearing systems. Additionally, our patented Ultra-Strap with a coining process provides a reliable and durable strap that is also rope-friendly. The central rivet on our 20mm and 30mm blocks reduces weight and offers a rope-friendly attachment for use in cascade systems.
