Rupp Quad Lok-Up Halyard Line Lock w/Bungee

The Rupp Quad Lok-Up Halyard Line Lock with Bungee is an essential control solution for sailboats and vessels requiring quick, secure flag and halyard management. This compact marine hardware is designed for skippers and crew who demand reliable line tensioning without constant manual adjustment—whether you're racing under time pressure or cruising long distances where precision rigging matters.

Built by Rupp Marine, the Quad Lok-Up features a four-point locking cam design that grips halyard line evenly without pinching or fraying the rope. The integrated bungee system absorbs shock loads and vibration, extending halyard life while reducing stress on cleats and rigging attachment points. Weighing just 0.6 pounds and measuring 5 x 2 x 8 inches, it's compact enough to mount on cabin rails, mast fittings, or bulkhead locations without adding clutter to your deck layout.

Boaters of all experience levels benefit from this line lock's one-handed operation—you can adjust or secure halyards while steering, managing sails, or working other critical tasks. The stainless steel and composite construction resists saltwater corrosion and UV damage, making it suitable for vessels operating in harsh marine environments year-round.
