Synchro single ring pulley - 50 mm

The Lewmar Synchro 50 mm single-ring block, designed for maximum speed and efficiency on board. Thanks to its optimized geometry and composite bearing, it significantly improves the efficiency of-mainsail hoists, while reducing friction on the rope for smoother operation. Its stainless steel flange provides real strength over time, while the stiffened cheeks limit the risk of jamming.

Practical for everyday use, the swivel can be locked without the need for tools, making it easy to switch from a fixed to a rotating position. With a working load of 450 kg and a weight of just 81 g, it combines solidity and lightness.
