Lewmar 60mm Synchro Triple Block with Becket & Cam – Black
The Lewmar Synchro 60mm Triple Block with Becket and Cam is built for high-purchase sail-control systems where smooth line handling and quick, secure adjustment are essential. The triple-sheave arrangement delivers efficient mechanical advantage, the integrated becket provides an additional line termination point, and the cam cleat lets you hold or release the working line instantly — without fumbling for a cleat.
Lewmar’s Synchro design uses optimized sheave geometry, a high-density free-spin bearing system, and a self-aligning head to minimize friction and reduce line wear across the full range of motion.

Parts Desk Insights
Best use case: This block is the right choice when you need a high-purchase system with built-in line control — the cam cleat makes it particularly well suited to mainsheet and vang applications where you’re frequently adjusting and holding load. The becket adds versatility for multi-part purchase systems.
With a triple block, matching line diameter and working load matters more than simply matching the outside block size. Proper line-to-sheave sizing lets the Synchro bearing system operate efficiently and reduces unnecessary wear on your running rigging. If your loads exceed the 800 kg WLL or your line is larger than 3/8", step up to the 72mm Synchro Triple.
