Lewmar Synchro Block Triple

Lewmar Synchro Block Triple

Product Description

The Lewmar Synchro Block Triple is a game-changer for sailors, designed to offer exceptional efficiency, superior handling, and reduced friction. Featuring a scientifically optimized block geometry, a Free-Spin bearing, and a self-aligning head, this block is engineered to reduce friction by up to 40% compared to standard blocks, delivering smoother and more efficient performance.

Each component of the block is meticulously synchronized with the movement of the rope, ensuring seamless power transfer from deck to sail. This synchronization minimizes rope wear, enhances durability, and maximizes the longevity of your rigging system.

The block is constructed with stainless steel straps to improve strength and service life, while the reinforced glass fibre cheeks prevent lines from wedging during operation, ensuring consistent performance even under heavy loads.

The 'Tool-Free' sliding swivel locking mechanism adds convenience, allowing for quick and easy transitions between swiveling and fixed shackles, providing versatility for different sailing configurations. Its large sheave diameter reduces rope friction, contributing to improved sailing efficiency.
