Harken 7411.11  MKIV Under-Deck Furling Unit 1 with 1/2" clevis pin

Designed for performance racing and cruising sailors, MKIV furling systems are strong, lightweight and aerodynamic, with the performance and features Harken is known for. Longevity, ease of use, and simplicity of installation are crucial components of the design. These free-rolling systems make all the difference in headsail control, allowing racers and cruisers to quickly furl and reef while maintaining great sail shape and optimal speed. Smoothly unfurl your headsail instead of hoisting a large genoa in light air. Now you can stay off the foredeck during a blow and rely on the furler for ‘crew’ when sailing shorthanded.

	Low-Friction Ball Bearings This strong, lightweight furler features multiple rows of Torlon® ball bearings in high-load areas to minimize friction for smooth furling. Bearings require no lubrication or isolating seals. Stacked bearing races in the halyard swivel evenly distribute radial and thrust loads to ball bearings; foils turn freely under halyard loads.
	Built to Last Foils and drum are securely connected with strong robust clamp to handle the high torque loads created when sails are reefed and furled in heavy air. Stands up to the Elements Deep-saturation Hardkote-anodized halyard swivel, line guard, torque tube and bearing races resist the corrosive effects of saltwater and sun and provide long-term wear. The line guard is also powder coated for added corrosion resistance. The drum cap is engineered from tough polymer resin.
	Durable Triple-Lock Foil Joints Tough triple-interlock foil joints withstand years of torque loading. Connector and geometric shape interlocks to foil and secures by coating engineered channel system with a syringe-injected adhesive. Screws provide a final lock.
	Easy Reefing and Furling The large inner spool diameter makes furling easier and a smaller outside drum diameter fits narrow bows or below deck. Independent halyard swivels furl sail center before head and tack for improved sail shape and upwind pointing.
