The Gloma 5/16" (8mm) Captive Pin Bow Shackle combines high-capacity rigging versatility with reliable on-deck security. Forged in Europe from marine-grade AISI-316L stainless steel, this shackle features a wide, rounded "bow" shape that allows for multi-directional loading and accommodates larger lines or multiple attachments with ease. Its standout safety feature is the captive pin design—the pin remains locked to the shackle body even when fully unscrewed, completely eliminating the risk of dropping it overboard during critical adjustments. With a solid 5/16" pin, a reliable working load limit of 1,600 kg (3,527 lbs), and a breaking strength of 3,700 kg (8,157 lbs), this shackle is the perfect worry-free hardware solution for anchors, halyards, and heavy-duty rigging.
