The 60mm footblock without jammer is ideal for turning lines along the deck, cockpit or any flat surface. Commonly used for spinnaker sheets, travelers, jib car systems, and more. The larger 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 maximize efficiency and reduce wear to both line and block. The cheek block or footblock version of these popular blocks features a solid aluminum base to protect the sheave and bearing from possible sealant egress and an aluminum cheek for additional durability and strength. Available with or without jammer.
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.
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.
