Harken Switch T-Track
Harken 18 mm Switch T-Track is machined or extruded from 6061-T6 aluminum and hardcoat-anodized for a long-lasting surface. For masts with sail grooves, 18 mm slug-mount track uses a unique system that allows mast-up installation. Use high-load slug-mount tracks on boats over 40' (12.2 m) at sail headboard locations at full hoist and when sail is reefed. Drill/tap track and switches fit masts without sail grooves. Join drill/tap track sections with splice links. Order one per track section. Boats with larger sail areas should use long switches to accommodate more cars.

18 mm High-Load:
Monohulls 45 - 50 ft (13.5 m - 15 m)
