5mm Shallow Bow Shackle

Harken 5mm Shallow Bow Shackle

The Harken 5mm Shallow Bow Shackle (Part No. 2132F) is a forged stainless steel shackle engineered for marine and sportfishing use. Electro-polished and tumbled to a high luster, the shackle features a shallow bow design that is proportionally wider for its length than a standard bow shackle, making it ideal for multidirectional load applications. The screw pin diameter is stamped directly into the body for quick on-deck identification, and breaking loads are measured with load distributed over 80% of the pin length — comparable to the load area of a block post — ensuring consistent and reliable ratings.

With a 5mm (3/16 in) pin diameter, a maximum working load of 540 kg (1,190 lb), and a breaking load of 1,080 kg (2,380 lb), this shackle is built to perform in the most demanding conditions. Its compact, proportional geometry allows it to fit into tight rigging configurations where a standard bow shackle would be too narrow. The forged construction provides superior strength and corrosion resistance compared to cast alternatives, and the high-luster finish resists the marine environment over long-term use.

This shackle is catalogued under Harken's Sportfishing line and is equally at home on sailing vessels requiring dependable complementary hardware. It is manufactured in the United States.
