The HARKEN classic - Midrange series blocks are designed for medium and large offshore yachts. Very robust, all blocks in this range are equipped with high quality Delrin ball bearings 76 mm sheaves for ropes up to 14 mm and reinforced stainless steel side plates.
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.
