Low-friction efficiency for easy furling and reefing

• Multiple 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.
• Foils rotate around 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, clear-anodized aluminum foils handle extreme reefing loads.
• Triple-interlock foil joints withstand years of torque loading: foil connectors geometric shape interlocks with foil; secure with syringe-injected adhesive; screws provide final lock.

Single-Groove Foils Offer Smooth Sail Handling

• Precision-extruded, single-groove foils for smooth sail handling.

Designed for Easy Installation

• Small outside drum dimension fits narrow bows or below deck.
• 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-LOK terminals.
• Eye-jaw toggle flips for fork or tang chainplate installation.

Easy to Maintain

• Bearings require no lubrication or isolating seals.
• Stainless steel link plates raise the drum and fit over existing turnbuckle, resist scratches, and can be re-polished.
