Harken MKIV Jib Reefing and Furling Unit 1

1. Free-Rolling Ball Bearings

Multiple rows of large-diameter Torlon® ball bearings in high load areas of the halyard swivel and drum minimize friction for smooth furling; Require no lubrication or isolating seals.

2. Strong Foil Joints

Tough triple-interlock foil joints withstand years of torque loading. Connector’s geometric shape interlocks to foil and secures with a syringe-injected adhesive into an engineered channel. Screws provide final lock.

3. Easy to Assemble Foils

C-shaped open connectors with low-friction plastic isolators slip onto the headstay wire and into foil for easy installation.

4. Drum Installs Over Existing Turnbuckle

Units are adaptable to a variety of rigging options for easy installation. Harken toggle assembly accepts standard turnbuckle using swage, rod, Norseman® or Sta-Lok® terminals. Toggle flips for fork or tang chainplate installation. A single stainless steel clevis pin provides access to the turnbuckle for adjustment.

5. Stainless Steel Feeder

Stainless steel feeder allows fast single-handed hoist and quick sail changes.

6. Removable Split Drum

Line guard and spool come off easily for racing.

7. Double Foil Grooves for Racing

Aerodynamic aluminum Air Foils® handle extreme reefing loads. Double foil grooves allow fast hoists, douses and sail changes.

8. Improved Sail Shape

Independent swivels furl sail center before head and tack for improved sail shape and smoother furling.
