Lewmar, Synchro Block Triple with Shackle, Black

The Lewmar Synchro Block triple black with shackle and three interchangeable pulleys has been designed for efficiency and extremely easy line handling. Optimised roller symmetry, a free-spin bearing and self-aligning block heads minimise friction while increasing the efficiency of the block in a mainsheet system by up to 40% compared to other blocks. Each block component perfectly synchronises line movement, which means a lighter and smoother transfer of load from sail to deck with minimum rope wear. Needle bearing blocks such as the Lewmar Synchro Block are typically used for high and static loads as halyard swivels, mainsheet systems, mast track blocks, masthead blocks or boom vang blocks. Features:

- Stainless steel support for maximum load-bearing capacity and long-lasting use
- Fibreglass-reinforced side sections to protect lines from jamming
- Innovative design with "tool-free swivel lock
- Large pulley diameter minimises line friction
- Heavy-duty free-spin bearing - reduces axle diameter for maximum efficiency
- Switchable from whirled to fixed block
- Discs can be replaced individually
