Harken 5mm Long Shackle

The Harken 5mm Long Shackle is a premium stainless steel rigging component designed for marine applications, sailing hardware, and heavy-duty load connections. Long shackles excel in scenarios where standard D-shaped shackles lack adequate clearance or load-bearing geometry, making them ideal for deck hardware, boom tackles, and multi-point anchor systems. This 5mm variant serves as a reliable link in modern sailing, commercial rigging, and outdoor equipment setups where durability and corrosion resistance are non-negotiable.

Forged from marine-grade stainless steel, the Harken 5mm Long Shackle is polished to a high luster finish that resists oxidation and maintains appearance in saltwater and freshwater environments. The distinctive long-form design proportionally extends the width-to-length ratio compared to traditional D shackles, distributing loads more effectively across the pin attachment point and reducing stress concentration. The screw pin diameter is stamped directly onto the body for quick identification in the field, eliminating guesswork during rigging assembly or maintenance checks.

Sailors, riggers, and equipment managers benefit most from this shackle when connecting to cleats, chainplates, or multiple-leg lifting arrangements where the extended profile prevents binding or cross-loading. The compact weight of just 0.05 lbs makes it suitable for weight-sensitive applications without sacrificing strength. Installation is straightforward—simply insert the screw pin through the eye, tighten, and lock; the stamped diameter marking ensures correct pin selection for future replacements or field repairs.
