Product details
Main sheet system with pre-assembled Gleistein TASMANIA ropes and matching blocks of LEWMAR.
Cleaning and Maintenance of Blocks:
Features:
- Sheet Ø: 12 mm
- Sheet length: 22 m.
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.
