I'm trying to install a duplex receptacle. The problem is that the hole in the wall doesn't have the threads for the screws that hold the receptacle to the wall.

I purchased a regular rectangular steel electrical box, but it doesn't fit in the wall; it's too big.

What options do I have?

Thanks.

  • Is this a standard drywall-and-studs wall? – ThreePhaseEel Jan 3 '18 at 23:14

    The box you have pictured is made for surface mounting on a shop wall. You may want a different style "old work" box if you're trying to recess it into an existing wall. More detail of the situation would help, such as a picture taken of the space this box is to fill. – Tyson Jan 3 '18 at 23:17

    Is it possible the hole is not intended for mounting electrical equipment? or could the correct holes be covered up by paint or leveling compound? – Harper Jan 3 '18 at 23:32
  • Yes, it sounds like you are trying to install an outlet box in a hole intended for low voltage equipment. – ArchonOSX Jan 5 '18 at 9:39

Is this already an existing box (just with damaged threads) if so then you can use some 1" #10 wood screws instead of the mounting screws that come with the outlet, this I a common problem I run in to on service calls (I am a apprentice electrician).

The other thing is that box you purchased is not a typical wall box instead you may want to try an 1104 box like this enter image description here

And if you are mounting it to the drywall instead of the stud (common when drywall is already up) use some f-clips to support itenter image description here it is hard to describe the installation in text so try this simple youtube video or you can use a rework box such as this as they are much easier to use but a bit more expensive (still under $10) enter image description here

I hope this helps

  • You should edit your answer and remove the reference to wood screws. Refer to "Article 406.5 Receptacle Mounting. Receptacles shall be mounted in identified boxes or assemblies. The boxes or assemblies shall be securely fastened in place unless otherwise permitted elsewhere in this Code. Screws used for the purpose of attaching receptacles to a box shall be of the type provided with a listed receptacle, or shall be machine screws having 32 threads per inch or part of listed assemblies or systems, in accordance with the manufacturer's instructions." Wood screws are not allowed. – ArchonOSX Jan 5 '18 at 9:37
  • Thanks for your comment. I think that's what I need. How would I search for a "1104 box" in an online store? – rbhat Jan 6 '18 at 2:00
