Smoothly unfurl your headsail from the cockpit of your boatDesigned for cruising sailors with strength, longevity and ease-of-use at a competitive price, these furlers feature the same quality materials as the MKIV furling systems. A single-groove round foil withstands extreme reefing loads, letting you easily unfurl your headsail, furl and reef safely in a blow. The foils are easy to assemble with interlocking connectors (screws and adhesive included) built strong for years of torque-loading. The drum installs over your existing turnbuckle, adapting to a variety of rigging options. The Harken(r) toggle assembly accepts standard turnbuckles using swage, rod, Norseman or Sta-Lok terminals, or fits directly to a marine eye. A single stainless-steel clevis pin provides access to the turnbuckle for adjustment. Features: Free-rolling Torlon(r) ball bearings Hardkote-anodized aluminum halyard swivels Line guard, torque tube and bearing races that are UV-stabilized and corrosion protected
