Harken 5mm Shallow Bow Shackle

The Harken 5mm Shallow Bow Shackle is a compact rigging component engineered for sailors and boaters who demand reliability in confined deck spaces where full-size hardware won't fit. Whether you're setting up control lines on a racing dinghy, configuring halyards on a compact cruiser, or managing sheet systems on a day sailer, this shackle delivers the dependable connection every experienced water handler knows is non-negotiable.

Designed for small-diameter lines and low-load applications, it excels where space constraints and weight savings matter—typical conditions you'll encounter on smaller vessels or auxiliary systems. Built from corrosion-resistant materials, the Harken 5mm Shallow Bow Shackle resists saltwater degradation and maintains its structural integrity through years of exposure to the marine environment. The shallow bow design minimizes snagging on deck cleats and prevents line chafe—a critical feature when every inch of freeboard counts.

At just 0.06 pounds, it adds negligible weight to your rigging while the compact 2 x 1 x 4-inch profile fits seamlessly into tight cockpit layouts or overhead installations where traditional hardware would interfere with sail trim or crew movement. This shackle is ideal for anyone upgrading block-and-tackle systems, building control line networks, or replacing wear-prone hardware on small-boat racing rigs. It works particularly well with 5mm line diameter, ensuring a snug, secure fit without the excess bulk of larger shackles.
