When a load fails at sea, there's no margin for error. The 316 Stainless Steel Bow Shackle is precision-engineered to hold under pressure — whether you're rigging a sailboat, towing a vessel, or securing heavy cargo on a commercial dock. With working load limits from 0.09 to 4.50 tons across a full size range, there's a shackle here for every job.
Rated for the Work, Built for the Sea
Each shackle is machined from marine-grade 316 stainless steel for maximum resistance to saltwater corrosion and mechanical stress. The threaded pin locks securely under load and won't back out during dynamic rigging operations — a critical safety feature for offshore and towing applications.

Sizing Guide
Select by A-size (pin diameter) to match your working load requirement. Larger A-sizes offer greater D-clearance for thicker chains and straps. If you're unsure which size fits your setup, contact us for a recommendation.
Note: Due to manual measurements, please allow for slight size tolerance. Always verify WLL against your application before use.
