Description

Improve line control and trimming efficiency with the Lewmar Synchro Triple Block with Becket & Cam, a high-performance sailing block designed for demanding yacht rigging systems. Combining three sheaves, an integrated becket and a built-in cam cleat, this versatile marine block supports high-purchase control systems and precise sail adjustments.

Featuring Lewmar’s innovative Free-Spin bearing technology and optimised sheave geometry, the Synchro block is designed to reduce friction and provide smooth, responsive rope movement. Its self-aligning head helps maintain correct rope alignment, while the stainless-steel strap and glass-fibre-reinforced side plates provide strength and durability for marine use.

The integrated becket offers an additional attachment point for control lines, while the cam cleat enables quick line engagement and release. This combination makes the block a practical choice for racing yachts and performance cruising sailboats requiring reliable, efficient rigging.
