Allen 20mm Dynamic Block with Hook

The A2020 is a top choice for dinghies, windsurfing, kitesurfing, and similar activities that require smaller lines. Its low friction design and lightweight but strong construction make it a go-to for fast movement. The Dynamic range utilizes a patented bearing system with twin rows of stainless-steel ball bearings on a stainless-steel rail for superior load-carrying ability and longevity compared to other systems with plastic rails. The built-in, articulated hook makes attachment quick and easy, and the large central rivet in our 20 and 30mm blocks offers not only reduced weight, but also a rope-friendly attachment point for tie-offs in cascade systems.
