    • Harken ESP Unit 1 Jib Reefing and Furling Systems are designed for day sailors and coastal cruisers looking for a well-designed, reliable, easy-to-assemble furler
    • Trim safely from the cockpit when the wind blows, and unfurl instead of motoring when it's light for a great day of sailing
    • Easy assembly and installation
      • Foils slip over standard marine eye and headstay wire for easy installation – no need to cut wire during installation
      • Adjustable bottom foil fine-tunes system length
      • Shackle at tack and head attach sail to furler, with sail shape controlled by halyard tension
    • Built to stand up to the elements
      • Spool made from hard lube-anodized aluminum
      • Cover, flange and guard molded from glass-reinforced polymers for high strength
      • Foils are clear-anodized for durability
      • Strong and durable stainless steel sail feeder
      • Single-groove round foil withstands extreme reefing loads for secure furling
      • Tough foil joints withstand years of torque loading
    • Long, medium or short leg kits for adjusting drum height
      • Choose long leg kit when using a turnbuckle with swage, Norseman or Sta-Lok® terminals
      • Long and medium leg kits raise drum to clear anchor, reduce sail chafe and increase visibility
      • Removable clamp screws allow legs to pivot out of the way for easy access to turnbuckle
      • Choose short leg kit when furler attaches directly to a marine eye at bottom of stay
      • Short legs allow sail to be closer to the deck
    • Optional halyard deflector installed above foil prevents jib halyard from wrapping around foil when furling
    • Lightweight stanchion-mounted blocks are available (order separately) for leading line aft to cockpit
    • 7-year limited warranty
