Harken 60 mm Double Aluminum Element Block with Swivel – 6269

Maximize control and performance on your sailboat with the Harken 60 mm Double Aluminum Element Block with Swivel (6269) — a high-strength, lightweight block designed for smooth, efficient line handling in a wide variety of applications. Featuring two sheaves mounted within a rugged aluminum element and a swivel head for dynamic alignment, this block delivers reliable performance for sheets, control lines, and traveler systems on cruising and racing rigs.

Harken’s precision-engineered aluminum construction provides superior strength-to-weight ratio and excellent resistance to the harsh marine environment, while the 60 mm sheaves accommodate mid-to-large diameter lines with minimal friction. The swivel head allows the block to rotate and align with changing lead angles under load, reducing chafe and optimizing sheeting geometry. With sealed bearings and smooth, low-friction performance, the 6269 Element Block keeps lines running easily even under high loads.

Whether you’re setting up mainsheet cascades, control line leads, or complex trimming systems, this double block with swivel brings versatility, durability, and precision to your deck hardware.

Summary for the User

The Harken 6269 is the "essential" choice for mid-sized keelboats and cruisers. It trades the complex bearing systems of racing blocks for a simpler, tougher design that excels at holding high loads for long periods. If you are looking for a reliable block for your mainshheet system or a heavy-duty boom vang, this is an excellent professional-grade option.

Maintenance Tip: Occasionally rinse the block with fresh water to remove salt deposits. Because the bearings are composite, they do not require grease or oil, which can actually attract grit and cause wear.
