The single block is developed for dinghies and smaller boats, where compact trim solutions and low friction are important. It provides smooth line routing in active control systems and performs reliably under varying loads. The block uses an acetal sheave with efficient ball bearing technology, ensuring easy rotation and dependable operation. The construction features a stainless center hub, providing strong mounting and stability in use. This model is used in mainsheet systems, cunningham, cascade systems, and other trim functions on boats up to approx. 4 m. The becket makes it possible to finish a tackle or start a purchase directly in the block. The compact size makes it easy to place close to the mast, boom, or deck fittings. The swivel attachment allows free movement and minimizes twist, ensuring smooth line routing.

USAGE INSTRUCTIONS Mount the block via the swivel attachment at a fixed point. Run the line correctly through the sheave. Check for free movement before loading and replace the line or block if there is visible wear.
