180 Degree Sofa Hinge 5 Level Folding Metal Ratchet Accessory

One sent me one? What does anyone do with one? These hinges operate poorly. They don’t lock into and of the positions. The lightest of touches moves it into the next click. They are made of cheap pot metal and will fail after one use if you can even find a single use for one. Save your money unless you absolutely know you need this. You’re better off bolting two pieces of wood together for a hinge.

These types of hinges are usually welded. I had to cut the old hinges out with a hacksaw and inserted the new hinges into the pipes. I drilled holes and used screws to keep them in place. Please be aware that these hinges need to be opened a full 180 degrees before they start latching. [Update] After two weeks the steel teeth have worn out completely in the region corresponding to the range that was used more frequently. The steel is not strong enough to hold the weight of a person that leans against two hinges. If you have such an application I would suggest that you throw away the piece of furniture that uses this type of hinges and buy a new one with a different mechanism.
