Patent-pending Harken Reflex Furlers give sailors confidence that their free-flying spinnakers and gennakers will furl with speed and control. The result Sailors use downwind sails more often—even when sailing shorthanded. The compact drive unit is easier to handle than other designs. Pull the furling line and the drive unit reacts reflexively to rotate the torsion cable, immediately transferring torque to the head swivel without unwanted corkscrewing delaying the response. The head swivel reacts instantly, spinning the sail smoothly and completely from top to bottom for an even roll-up and super-tight wrap. The furled spinnaker lowers easily to the deck, ready for the next hoist.The Reflex cable is torsionally resistant to corkscrewing. Braided stainless steel wire filaments over braided polyester core transmit torque to head swivel through both tension and compression for faster furling. Textile cable transmits through tension only.The quick-release modular T-fitting allows a single drive unit to handle multiple sails.Complete Unit 1 Reflex Top Down Furling Kit includes:Lower drive unitHead swivelTack swivel terminalSnap shackle threaded adapter60' torsion cable and clamps
