Allen 30mm Dynamic Swivel Block with Hook

The A2030 Dynamic Swivel Block with Hook features a single 30mm pulley that is ideal for dinghies, windsurfing, kitesurfing, and other activities with small diameter lines. It has a lightweight yet sturdy design and is known for its low friction and fast rolling capabilities. The built-in swivelling hook allows for easy attachment and removal and can also align with changing pulling forces, though it cannot be locked. Additionally, the block utilizes a patented bearing system with twin rows of stainless-steel ball bearings for exceptional load-carrying ability and longevity. The 20 & 30mm blocks also come with a central rivet that reduces weight and offers a rope-friendly attachment for use in cascade systems.
