Product details

  • Side panels made out of high-quality UV-resistant plastics
  • 50 x 14 mm pulleys made out of high-quality UV-resistant plastics
  • Light weight
  • Made in Germany
  • Excellent price-to-performance ratio


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.

Excellent block
I bought the block in the shop in Kiel and am completely satisfied - I use it as a block for the jib sheet, where it does its job bravely.
