Lewmar, Synchro Block Single Shackle HF, Black

The Lewmar Synchro Block Single Shackle HF (Hundsfott) black was designed for robustness and extremely light line handling. Optimised block symmetry, free-spin roller bearings and self-aligning block heads minimise friction while increasing the efficiency of the block by up to 40% compared to other, cheaper blocks. Each block component perfectly synchronises line movement, which means lighter and smoother load transfer with minimal rope wear. Features:

• Stainless steel carrier for maximum load capacity and long-lasting use
• Stiff, fibreglass-reinforced side panels to protect lines from jamming
• Innovative design with "tool free swivel lock switchable from swivelled to solid block
• Large pulley diameter minimises line friction
• Heavy-duty free-spin bearing - reduces the shaft diameter for maximum efficiency
