This low-friction ball bearing Tack Swivel Terminal is for use with the Harken Reflex furling system and allows the upper part of an asymmetric sail to furl first. The rolled sail easily disconnects with the pull of one spring-loaded pin, and a new furled sail slides and locks into the furling unit's T-slot. 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 Tack Swivel Terminal is included with each Harken Unit 2 Reflex system. Order with Reflex Head Swivel 7352.28 for additional asymmetric sails.
