Factory Supply 360° Rotation Spring Door Hinge Nickel Plated Durable Construction

Most people don't realize these won't work on every door right out of the box—the adjustable closing speed is what saves you, but it still needs a bit of fine-tuning to get the tension right for heavier doors. It's not a set-it-and-forget-it thing. They're surprisingly solid once dialed in.

The nickel plating does more than look good, it actually stops rust from creeping in at the hinge pins, which is where cheap ones fail after six months or so. 3. You get either 201 or 304 stainless steel depending on the batch and your budget, with 304 being better for damp environments or exterior use—most buyers go with the 304 for peace of mind. It handles composite and metal doors fine, but we've had some buyers run into trouble with ultra-thin wooden doors (under 35mm) where the screws can pull.

Sizes run from 3 inches up to 8 inches—the 5-inch size is by far the most common for standdard interior doors, though you might want the 6-inch for heavier commercial applications. Avaliable in black, gold, bronze, or nickel, with the nickel being what's in stock most of the time (usually 2-4 weeks lead time if you need another color).

Basically, these are meant for appliction where you need doors to swing both ways and close quietly—think restaurant kitchens or hallway flow—not for home front doors that need heavy latching. The 360-degree double action is the real feature here, letting the door open a full 180 degrees in either direction.
