HARKEN PROTEXIT Indeck Double Block / double-sheave / 8 mm / plain bearing

The Harken Protexit In-Deck Double Block is a high-quality and functional double block designed for flush installation in the deck—ideal for clean and safe line routing without protruding hardware.
With two sheaves arranged side by side, this double block offers excellent flexibility for guiding multiple lines simultaneously. Free-running ball bearings ensure smooth, low-friction operation and efficient power transfer, even under high loads.
Its robust and durable construction, made from high-quality materials, guarantees reliability and stability in demanding sailing conditions. Thanks to its space-saving in-deck design, this double block is particularly suited for sheets, halyards, or control lines on dinghies, sport boats, and yachts where a clean deck layout and functional integration are essential.

Characteristics:

• Double block for flush in-deck installation
• Two sheaves for flexible and efficient line guidance
• Low-friction ball bearings for smooth running
• Robust and durable construction
• 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.
