This low-profile head swivel is for use with the Harken Reflex furling system. An integral thimble terminal for the torsion cable saves weight by eliminating eye and pin connections. This swivel can only be used with Harken Reflex torsional cable and clamps. The compact bearing system reduces weight aloft, while the low profile maximizes luff length. Each head and tack swivel stays with its sail permanently and is stowed together, ready for the next deployment. A padded cover prevents damage to spars. One swivel is included with each Harken Unit 1 Reflex system. Order with Tack Swivel Terminal 7351.26 for additional asymmetric sails and with Fixed Tack Terminal 7351.27 for code zero sails.
