HARKEN ZIRCON Triple Block with Becket / 3-sheave

The Harken Zircon triple block is a robust and versatile triple block from the popular Zircon series - ideal for demanding line guides on board. Especially for more complex trimming systems, this block features three sheaves arranged side by side, allowing multiple lines to be guided efficiently and flexibly at the same time.
The low-friction ball bearings ensure all three sheaves run exceptionally smoothly, providing efficient power transfer even under heavy loads. Its robust and durable construction makes this triple block a reliable choice for sheets, halyards, runners, or other heavily used control lines on dinghies, sports boats, and yachts.

The 40 mm Zircon Triple Block is a versatile all-rounder for recreational and performance sailors, offering a compact, high-performance, and long-lasting solution for managing multiple lines with ease.

Properties:

• Triple block from the Harken Zircon series

• Robust, durable construction
• Three sheaves for flexible and efficient line guidance
• Perfect for sheets, halyards and multiple trim lines

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.
