The plate buzz shows has four holes, spaced to mount to ANY box cover or two-gang box.


What on that plate shows that the box behind the plate must be a 4 inch box? I see four holes that will line up with any set of screw holes for a two-gang cover.


In residential use, I've seen four inch boxes, boxes made from old-work boxes that gang together, and two-gang PVC boxes. All of those setups have exactly the holes that would line up with the plate he showed.


Guys, he wants a plate to hold a one gang device on a two gang box. Buzz shows the proper product for that.

I fing give up. The metal plate shown mounts to a 4.25x 4.25 welded metal box in the corners. These are not typically seen in residential or inwall environments. The device mounts to that metal plate and cover mounts to device. That backplate does not have holes to mount in a standard 2 gang in wall box. If he has the metal box inwall great. The cover with 6 holes might do the job again. If he has a standard 2 gang box. But who wants to see 6 screws.
Maybe we need a picture of existing box type

I think it would look best to go with a custom cut adapter plate that fits in the depth between the mud ring and the drywall...so that you could use a 2 gang plate like Daniel posted above. I think this will look the cleanest. You could measure the opening and have a local metal shop cut you 1/16" plates that you could pilot (for the 4 screws to attach it) and tap/thread 2 center screws for your decora screws.

I did find two different adapter plates that require no Kustom work. These would get mounted then your decora device monted over them...then your decora plate over that. So it would be stacked. This wont look perfect but it should be fine. Maybe go with a screwless single gang decora plate to clean it up.

I would probably order one of each to see which A.Works B.Works/looks best.

That product would be PERFECT if it were a screwless plate design. While i think the 4 visible screws will be distracting...it should get the job done.

To the OP...Be careful not to damage the paint on the screws and line them all up the same direction.

If one can remove the original box, then suspend a new single gang ring with Madison Bars or a block out from a nearby stud, then Daniel's plate would work.

Ideally a screwless 2G -> 1-G adapter plate exists somewhere.

Visually, it may be best to find an excuse to add a second device to the box and use a standard 2-G ring.

While I don't like them for this sort of application, a blank Decora insert is another path.

I don't know how the color and finishes might match. One would mount this plate, the keypad, then overlay a screwless Decora ring. The big advantage would be that everything is off the shelf.  The disadvantage is that it might have an overall "patch job" look.

It depends on the surrounding. I once wanted to use a blank plate in hte livingroom in order to pull around a fire break. He called his wife and the three of us went round and round until I asked them to tell me where there was an existing blank plate. After 15 minutes they returned, failing to find the blank. (It was in plain sight in a kitchen soffit. I had cataloged it within seconds of entering the unit.) Then I pointed out that my blank would be buried behind the drapes. One would probably not bury a keypad behind the drapes, but some people don't want to be able to see any technology. I have one customer who didn't want to see any light switches from the livingroom -- they are all down the hall. To me this seems very inconvenient, but I don't live there.
