LEWMAR 60mm Synchro Double Block - Swivel, Becket, 2992-6005

A unique block that is synchronized with running rigging systems.

The 60mm double block with becket is ideal for mainsheet systems and boom vangs. The medium sheave diameter works well with up to 3/8" lines.

Synchro blocks combine geometry, sheave ratios, and a unique Free Spin bearing to deliver performance that’s comparable to ball and roller bearing blocks used in racing but at a more affordable price. Designed to optimize the relationship between block and line, these blocks have self-aligning features to maximize efficiency and reduce wear to both line and block. An innovative sliding mechanism controls the shackle post swivel. With the flick of a switch select between full 360° free rotation or one of two fixed settings (0° or 90° to sheave axle). Both fixed positions provide 30° of rotational “float” to allow the block to self-align to the system.

Synchro blocks use a larger sheave that features the Free Spin bearing. The bigger diameter sheave prevents distortion and reduces line wear while the Free-Spin bearing handles higher static loads. A stainless steel shackle post and framework support the glass fiber-reinforced cheeks to increase block strength while minimizing overall weight. The molded cheeks guide the line and prevent wedging.

Designed to be synchronized with your boat’s running rigging systems, Lewmar Synchro blocks are an ideal choice for the sailor looking to get more for less: racing features at a cruising price.
