The fixed tack terminal option is used when the torsion cable is inside the luff. Tack swivels are available with fork and pin interfaces to allow sails with existing torsion cables finished with eyes to be easily adapted to Reflex furling. Quick-release modular T-fitting allows single drive unit to handle multiple sails. Rolled sail easily disconnects with the pull of one spring-loaded pin; new furled sail slides and locks into T-slot.
