Product details

Fiddle blocks (AP) are suitable for for long-term, reliable and maintenance-free operation, thanks to their great capacity. They are designed for heavy loads and have a long life.



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.

Simple block with good utility
On our Sirius 32DS, we use these blocks as a quick way to secure the furling lines for the genoa and jib. They are fixed to the aft railing. After furling, the furling line is simply secured in the cleat. There's no need to cleat it.
