Lewmar Synchro Block Double

Product Description

The Lewmar Synchro Block Double combines superior speed, efficiency, and handling. Designed with scientifically optimized block geometry and a Free-Spin bearing, it reduces friction by up to 40% compared to budget alternatives. The block is available in multiple diameters, including the Lewmar Synchro Block Double (Diameter: 60), Lewmar Synchro Block Double (Diameter: 72), and Lewmar Synchro Block Double (Diameter: 90), catering to varying needs for different sailing applications.

Each element of the Lewmar Synchro Block Double is perfectly synchronized with the rope, ensuring smooth and efficient power transfer from deck to sail, which reduces wear on the rope and enhances overall sailing performance.

The block is constructed with stainless steel straps for improved strength and long service life, while the reinforced glass fiber cheeks help prevent line wedging. The 'Tool-Free' sliding swivel locking mechanism allows easy transition from swiveling to fixed configurations, ensuring convenience for different setups.
