Product details
Double block with swivel.
LEWMAR - SYNCHRO blocks:
The incredibly streamlined block geometry, the revolutionary low-friction bearing and the self-aligning block head result in reduced friction of 40% compared to conventional mainsheet systems. Each block component is synced with the line movement, resulting in a lighter and softer transfer of the load from the sail to the deck - and all this with hardly any line wear!

Cleaning and Maintenance of Blocks:
- Rinse blocks regularly and thoroughly with warm fresh water to remove salt and dirt (carefully assist with a soft brush if necessary).
- For heavier soiling: Soak the block in warm fresh water with a little dish soap and move the rollers (do not use harsh cleaners).
- Avoid pressure washers, as water and dirt can be forced into the bearing.
- Allow to dry thoroughly afterwards to prevent corrosion.
- Lubricate only when necessary and according to the manufacturer's instructions.
- Note: Many modern bearings are maintenance-free or self-lubricating – improper lubrication can impair their function.
- Disassemble only if explicitly instructed by the manufacturer, as not all blocks are designed for maintenance or disassembly.
