The
Harken Zircon double block is a reliable and versatile double block for a wide variety of line guides when sailing. The popular Zircon series offers excellent value for money and solid performance for recreational and sports sailors.
Thanks to free-running ball bearings, both sheaves run particularly smoothly and ensure efficient power transmission. The robust design makes the double block durable and reliable - ideal for sheets, halyards, runners or other trim lines on dinghies, sports boats and yachts.

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.
