This is a straightforward but super useful piece of marine or general hardware: a folding D-ring pad eye. When you need a strong tie-down point or attachment ring on your boat deck, truck bed, trailer, or even in a workshop, but you don't want a permanent protruding cleat getting in the way, this is your solution. It's made of stainless steel, so it's resistant to rust and corrosion, especially important near water. The ring itself is a D-shape and it folds flat against the base when not in use – that's the key feature. When you need it, you just flip it up, and you've got a solid 2-5/8 inch ring to hook a rope, strap, or carabiner onto. The base has holes for mounting it with screws or bolts. It's a simple, no-nonsense, heavy-duty fitting. \Best in class\ might be their boast, but for a basic folding ring, it does exactly what it's supposed to do: provide a secure, low-profile attachment point that you can stow away when you don't need it. Great for keeping decks clear and safe.
