b'Designed for easy installationSmall outside drum dimension fits narrow bows or belowdeck. C-shaped open connectors with low-friction plastic isolators easily slip onto headstay wire and into foil. Drum assembly fits over existing turnbuckle allowing easy length adjustment. Harken toggle assembly accepts standard turnbuckle using swage, rod, Norseman, or STA-LOKFoil terminals.SD BoatWorks connectors Eye-jaw toggle flips for fork or tang chainplate installation. Toggle assemblyLow-friction efficiency for easy furling and reefingMultiple rows of Torlon ball bearings in high-load areas minimize friction.Stacked bearing races evenly distribute radial and thrust loads; drum and halyard swivel turn freely under load. F oils rotate around headstay so headstay load is isolated from the furling unit for easy furling. Large inner spool diameter increases mechanical advantage for powerful reefing and furling.Stands up to sun, salt, and time Aluminum line guard, torque tube, and swivels deep-saturation hardcoat-anodized, UV-stabilized for durability. Line guard polyurethane-coated for wear protection.Specially formulated low-stretch black line is abrasion and UV-resistant; standard on units 0, 1, 2.Round foils handle extreme reefing loads.Triple-interlock foil joints withstand years of torque loading: foil connectors geometric shape interlocks with foil; secures with syringe-injected adhesive; screws provide final lock.
