Plastic box extenders

[Eddie702]

I know they make both plastic and metal box extenders for when a box is set too deep. Is there any reason you can't use a plastic box extender with a metal box provided of course you bod the device to the metal box?

Should not be an issue

If you had a plastic box and used a metal box extender, then you would have to ground the extender.

Agree. TY

Or just use 3” screws

The plastic also avoids wire/terminal contact concerns.

 

[Eddie702]

Yes. In fact, I have a couple of the Arlington ones. I just checked on their site, and they are saying it can be used in plastic or metal boxes and prevent the wire /contact that @LarryFine mentioned and they are good for a 1 1/2" set back.

A good problem solver.

Seen this too many times to count, especially on tile jobs.

If you're in the Chicago area.

When I used to do houses that was the first question I asked. 'What's going on the walls and ceilings? I am assuming everything is 1/2" sheetrock unless you tell me otherwise. Except for the attached garage which is usually 5/8". But you sometimes couldn't get a straight answer.

When there is 24 inch centers on ceiling framing it generally gets 5/8 rock because 1/2 inch rock may sag over time.

I could see some inspectors thinking you should use metal extender in places of assembly if there is any other situation where non metallic wiring methods is normally prohibited.

I don't think there is a code section that would specifically address the box extender type in this situaiton though.

I did a cabin for my cousin a couple of years ago, he said wall and ceiling finish was 3/4” tongue and groove. Turned out to be 2 1/2” tongue and groove on the ceiling, and 1” on the walls! Did I mention he owned a large sawmill business?

did he need beefier framing to support the weight?

Or they put strapping up even with 1/2".

I can't recall ever running into that on totally new construction. Existing construction can have various reasons to add the strapping
