The Allen A2020 is a top choice for dinghies, windsurfing, kitesurfing, and other activities that require smaller diameter lines. Its Dynamic range offers excellent sheave movement, thanks to our patented bearing system that uses twin rows of stainless-steel ball bearings. In addition, the P-Clip accessory allows for easy mounting on any surface. The block is also equipped with our unique Ultra-Strap, which is strengthened through a coining process, making it durable and rope-friendly. Additionally, the central rivet found in our 20 and 30mm blocks offers a lightweight and rope-friendly attachment point, perfect for use in a cascade system.
