Hi all, I've used metal architrave back boxes behind some wall lights for the connections, and I've got a blanking plate with a hole drilled though it for the cable supplying the lights.
The issue I have is that the screw holes in the blanking plate don't match with the lugs in the back box. They are about 5mm off both sides. The blanking plate is in fact almost exactly the same size as the metal back box, which doesn't seem right to me.
As I see it, I have 2 options:
1) drill through the back of the back box and use long screws. I don't like this as they are quite busy with wires, and I don't want to nick anything with a screw, and one of the screw holes lines up with the earth connectors in the back box.
2) rip out the metal back boxes, and sink a surface mounted plastic in the hole, which have the lugs in the same position as the blanking plates.
Does anyone have an option 3? Tried glueing the blanking plates on, but they keep moving before the glue sets.
