Default Adding electrical boxes

I need to add several in my new remodeled room. Is there some way that I can just cut a simple clean square without the tab area (see my last addition) to the right that I have to fill later. I hate doing sheetrock work. Is there a simpler method once I find the wires and stud??? or Is there something to fill this 1 by 2 inch tab that wont shrink. Cutting a small chunk of sheetrock is a pain in the but.

All ideas welcomed!! - pic should appear in a few minutes...

They make a box that has 'wings' on them. after sliding the box into the hole the 'wings' will swing out behind the dry wall and you tighten them via a screw... The tace cover then covers the opening

Home Depot sells them here in my area....

The boxes are called "old work" boxes. They make them in many styles. Very simple to install and no f'in around with plaster or SR. They are also flush on every install, wood or plaster. I have not had the greatest of luck with the plastic old work boxes but they do work. The limiting factor is the thickness of the wall. I was needing them on the exterior walls as we did not know what box would be needed for the yet to be picked out light fixtures. They are good for 1/2 - 5/8 thick walls.

They also make Madison bars for adding steel boxes to old walls. It's a thin steel stamping that you insert behind the wall and fold over the tabs onto the box. They work OK but not great. Look for the proper box for a solid job.

If you stay away from the plastic boxes there are many ways to do it. It will however cost you a little more for the steel ones.

Marker has it spot-on. Just expaned some outlets and relocated others and these worked well. You'll see the plastic boxes marked "Old Work" and "New Work". You want the "Old Work" as these have the wings that flip up and clamp against the wall as you tighten the screws. Just be careful you don't go too big with your cut-outs so there's enough wall for the wings to catch.

The plastic ones I've seen have diagonal nail guides on the inside, and no flange.

Use remodeling boxes, or also referred to as "old Work" boxes, or even sometimes referred to as battleship boxes.

I also recommend metal - costs a bit more but easier to work with.

RI Builder and MisRest-

Can you elaborate more on metal boxes being easier or providing more options versus the plastic ones? Would welcome your input as I've only used the plastic ones and found them to work OK (weekend warrior here). Always looking for more input/advice and can always use an excuse to pop a hole in a wall to try something new. Have tried the Madison bars before with poor results - could never get a tight fit or strong box hold.

Thanks in advance.

Alex

As an electrician with a license, I can use both types of boxes with amazing results, and your home will not burn down.

And do you have the bumper sticker that reads "Wiring is not a hobby? Hire a licenced electrician".


Says who?

Alex, I just prefer to use metal boxes for old work. It's just me. I'm a little old school and that's how I learned. My new house is all plastic wall boxes because they are fast. When I wire my shop space in the basement it will all be in steel. I have the boxes and EMT, all I need is the time but I'll get to it. I think it mounts better to the concrete walls. Plastic is,,, well,,,, plastic. There's a time and place for it.

In ME you don't need a licence to wire after the main breaker. I still had my regular crew do the job as it was a little detailed with an auto X fer switch, gen set, and mostly scene lighting throughout. I did a fair amount of the cat 5 and CATV. I did all of the home theater, sound, and alarm wiring. I've worked very closely with these guys for 15 plus years. Mostly complicated, very large residential. I ain't burned anything yet but I have let the smoke out of some wires.

It is just a preference thing. Both are usable, but I just prefer working with the metal boxes. As for specific upsides, well they do not burn and are more durable.

No - the one that says "Let a licensed electrician remove your shorts."

Thanks for the reply, LI and Mist-Rest. I have used the metal boxes in the basement and garage (the garage is this weekend's project, actually) - agree about the block wall application.

Hold the phone there batman, you are totally wrong! If your talking about a cabin in the backwoods with no AHJ thats a different story, otherwise you are wrong!
