Product details

Fiddle block with swivel, becket and cleat.
LEWMAR SYNCHRO blocks:
The incredibly optimized block geometry, the revolutionary free spin bearing and the self-aligning head of the block ensure 40% friction reduction compared to conventional system. Each component of the block is synchronized with the line movement for an optimised transfer of load from the sails to the deck, all with extremely low line wear. Shackle post locks by pressing a button.

Care advice

Cleaning and maintenance of blocks:
  • Rinse blocks regularly and thoroughly with warm fresh water to remove salt and dirt (if necessary, carefully use a soft brush).
  • For heavier soiling: soak the block in warm fresh water with a little detergent and move the sheaves (do not use aggressive cleaners).
  • Avoid pressure washers, as water and dirt may be forced into the bearings.
  • Then allow to dry thoroughly to prevent corrosion.
  • Lubricate only when necessary and according to the manufacturer's instructions.
    • Note: Many modern bearings are maintenance-free or self-lubricating – incorrect lubrication may impair function.
  • Disassemble only if explicitly intended by the manufacturer, as not all blocks are designed for maintenance or disassembly.
