Hi ,

I need a 3" Round Duplex Receptacle Cover or 3 -1/4 inch (I don't know exactly)
However I can only find it in 4 inches.( ironically I did find covers )

(I need it for a 'old' deep round metal electric box that is apparently less then the standard 4'' size of today's round box's)

Will this work?

You can use a 4", just drill holes to line up with the box ears or cut one down.

I'd replace the box. Those small boxes and covers are no longer legal size for a reason.

THANKS! That is what I was looking for ,although its designed for octagonal box's it can obviously be used for round box's.

you have a point however its not recommended to mess around with old wiring from before the 60's.

Today I was working in a 50's vintage attic and was wondering why the 4" square box in the attic was suspended a couple of inches above the drywall. 3" round box in ceiling connected to a hickey connection and into the 4" box. First 3" box I have seen. Boy, they are small. Had 3 pieces of 14/2 into the 4" and pigtailed wires down the hickey into the 3". I would have used a new work deep ceiling box.
