HARKEN 76 mm Classic Block - Swivel, Heavy Duty, Becket, 012

Strong, dependable, and exceptionally free running, these blocks are the foundation of the Harken line, with a vast library of hardware choices available to complement your boat’s style. Classic blocks come in multiple sizes, and dozens of configurations and are ideal for almost every trimming task. Ball bearings, sheaves, and sideplates are UV-stabilized with carbon black for maximum protection. Stainless steel straps reinforce blocks and resist corrosion.

The 3.00 (76 mm) blocks are compact and lightweight, with fast trim and release under high or low loads. Perfect for dinghies, scows, beachcats, and iceboats, as well as small offshore racers and cruisers.

Note: Special Order Only

• Set screw allows shackle to be fixed or to swivel
• Free-running ball bearings roll on flat races with minimal friction
• Large diameter sheaves reduce the friction caused by bending line over a small sheave
• When using single blocks on keelboats and offshore boats and other applications where the load is high, use the heavy duty 011 or 012, which have a tougher shackle and head post
• Ideal for situations where a lightweight block is required to carry wire
• High-load wire blocks use Torlo®n ball bearings for a higher working load and are used for applications such as halyard lead blocks on masthead boats to 30'
• Use for main and jib sheets, spinnaker halyards, and control lines
