It's the kind of simple, strong connector you reach for again and again, joining an anchor rode to chain, shackling a block to a padeye, or rigging a line on deck. Threads apart by hand, holds tight once you snug it down.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eA D-shackle earns its keep by being predictable. The straight sides and U-shape rounded bottom keep the load running in a straight line, which is exactly what you want when you're connecting an anchor rode to chain or hanging a block off a padeye. This Sea-Dog version is cast from 316 stainless steel, so it shrugs off salt spray and stays bright season after season.\u003c\/p\u003e\n\u003cp\u003eThe screw pin is the handy part. It threads all the way out when you need to open the shackle, then snugs back down by hand. No special tools, no fuss. Just remember to seize the pin with a bit of wire or thread-locker if the shackle is headed somewhere it'll see constant motion, because a screw pin can back off over time.\u003c\/p\u003e\n\u003cp\u003eWith a 5\/16 inch pin and an 11\/16 inch ring, it fits a lot of the everyday rigging jobs on small and midsize boats. It's sold as a single shackle.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e316 stainless steel casting for marine-grade corrosion resistance in saltwater\u003c\/li\u003e\n  \u003cli\u003eScrew pin threads fully out by hand for quick connect and disconnect, no tools needed\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch pin size\u003c\/li\u003e\n  \u003cli\u003e11\/16 inch ring size\u003c\/li\u003e\n  \u003cli\u003eD-shape body with straight sides and U-shape rounded bottom for straight-line loading\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sea-Dog reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat is this shackle made of?\u003c\/summary\u003e\n    \u003cp\u003e316 stainless steel.
