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.

The removable bar is worth its weight in gold.
This is the only way to remove blocks from fixed U-bolts without having to dismantle the bolster itself.

The wear rate of the rollers is quite OK at the price, but a bit high with around 3 years of use with average use.
