40mm Control Blocks
Through a combination of geometry, advanced materials and a unique Free Spin bearing, Lewmar created a block that performs as well as pro racing blocks at a fraction of the cost. Molded MRT sheaves and composite cheeks reduce weight and roll resistance and improve impact resilience. Design versatility also makes the Synchro Control 40 suitable for everything from control blocks on superyachts to dinghies.
