When replacing a broken light above a door, I found there was no junction box, just very old wires going through a hole in the plaster. This box/pot was just what I needed to get the job done quickly. The box is riveted, the wiring is secure in the box, the bracket is securely attached to the box, I didn't have to do anything with the wires or the hole they already went through, and the bracket didn't stick out too far either .
