Long D Shackle, AISI 316 Stainless Steel

The Long D Shackle is a heavy-duty D-shaped shackle with an elongated body, crafted from premium AISI 316 stainless steel. This robust construction ensures high load capacity and excellent resistance to rust, even in harsh saltwater environments. The shackle’s extended length provides extra clearance, making it easier to connect with bulky rope thimbles, chain links, or multiple attachments without binding. The screw-pin closure locks securely in place to prevent accidental opening during use, giving you confidence in critical connections on board. This shackle is forged and polished, delivering a smooth finish that won’t snag lines and adds a professional look to your marine hardware.
