Is there a term for a trim piece that surrounds a surface mount electrical box to accomodate a flush install? I'm replacing some exterior lights by our garage, but all the lights my wife has selected are either intended for a flush mount or do not have enough space to accomodate the existing electrical box, so they leave a gap. I could make something out of plywood but would prefer a more finished product.
Update: Ended up removing the box and attaching the lamp directly to the wall. Of course the mounting plate holes didn't line up, so I had to rivet a j-box cover to it and drill appropriate holes. Spray painted the plate for rust prevention.
