Q:When using the side tab and nailing to the face of the stud, how to you avoid a drywall bulge caused by the tab?
by|Jan 10, 2023
1 Answer
Answer This Question

A:  Hi StorageGuy, I didn't have any problem with the tab causing bulging under the drywall. I believe the main reason for this is that I chose to screw the boxes in as opposed to nailing them in. I found it easier and faster to install them this way. By screwing them in I was able to guarantee a very snug and secure placement ot the boxes. I did this for all my boxes. for switches and outlet placement. You may find that this cost a small amount more but it really is an easier and faster way to mount the boxes. I hope that helps.

    Q:The boxes I bought measure 1/2 in from the ear that mounts on stud to front of box do they make same box for 5/8 drywall ?

    Answer This Question

    A:  Article 314.20 of the electrical code, it is stated that boxes should be mounted flush with the finished surface of the wall, with a maximum setback of no more than 1/4 inch. If you only have a few. rip some 1/8" paneling an shim the box out. I suggest talking to your local building department for you area. You can also check with the manufacturer.

      A:  Use a 5/8 plywood block as a depth gauge and break off the mounting ears and use the nails to mount to the side of the stud.

        A:  No I think you have to cut that off for deeper application

          Q:Should the knock out tabs be removed or just made wider open?
          by|Mar 6, 2021

          Answer This Question

          A:  Hi SushiBreath, well being a real electrician you dont remove the wire insulation until it is in the box then you can use a knife to do a soft cut in the insulation sideways (not length ways) the pull on the insulation and remove the outer cover. But you are wanting to remove the insulation first then stuff into the box. The tabs are not to be removed they hold the wire in the box and help keep critters out of the box. Real electricians dont remove the tabs as they are required by code and if you have a fire etc and a good inspectors sees that the removal of tabs had anything to do with fire they dont pay and selling the house if this comes up you could be in trouble. And if much easier to pull 14/2 in the box if you do it the correct way. I have wired 1000's of houses and I and most other electricians do it the correct way.

          A:  They are designed to keep the wires from pulling out of the box and exposing the bare wires. They are very tight and generally I loosen them up a bit with a screwdriver, but don't remove them. It defeats the design.

          Single Gang Box
          These worked great for adding new outlets for a renovation. They were easy to install, easy to wire, and attached to wood studs perfectly.

          A box I can screw! I wish I had this years ago! Mounts easy, and solid! Covers most house wiring needs. Carlon makes great boxes for any specific application. But I often run out of the models I use most, forcing a mis-fit or a trip to the store. Also, I have never been good with nails. Air-nailers and screw-guns have spoiled my aim. The feature I LOVE is the screw fixtures. Ordinary drywall screws into the interior or the breakaway flange will set the box tight and right. I have often run an extra screw inside the box but this was not Code-Legal (sharp screw-heads in wire zone). This box has screwholes with recesses and is fully Approved for screw-mounting. I'm a wizz with a screwgun. I also love the way this one model adapts to New or Old Work. I'm renovating an old house, a mix of new and old work. Normally I would need several boxes of boxes for the different situations. This one box will do 90% of my project; just one case to lug around. The Carlon B125AB New/Old-Work box can be nailed to bare stud (before drywall) as a New-Work box. And when you can't swing a hammer, you can screw it. The side-tab sets the box perfectly for drywall. Bring your wires in, done! For Old Work: Find the side of a stud. Mark your hole and cut-out. Break-off the box breakaway side-tab and remove nails. Bring your wires in. Slide box into hole and run drywall screws into the handy internal screw-holes. Done! Internal wiring is easy: this box is nearly as deep as a stud! There's ample space inside a wall for easy maintainable wiring, this box gives you the most you can get in a single-wide. While a Big Contractor can afford to stock every just-right box size, us small-job workers are better-off carrying just one model box as big as can be. 20 cents more depth is a lot cheaper than a too-small box and a failed inspection. A small feature: when your client or tile-contractor says the boxes have to move, un-screwing is less violent than prying nails out. Some of the small low-price blue-boxes are a little flexible. These are quite stiff and should not twist out of square when you install devices. One thing this box won't do easily: mounting away from any framing. You still need a few of those back-clamp boxes for when the client demands a box in the middle of a stud-bay. I have one mild complaint about my (early production) sample. The cable clamp is very hard to open up even with a fat screwdriver. The break-aways don't clear and the clamp finger gets deformed. I think Home Depot should stock a LOT of these boxes in the front of the electrical aisle, sold individually or by the 24-case. They really are a better product than most of the special-purpose boxes now offered.

          Wow, I have landed these boxes off and on for years, as of lately, most of the boxes have felt, succinctly "CHEAP". Well, these boxes have some weight to them, do not flex, and even the anchor nails appear to be "Galvanized, Zinc coated or something". They actually sit vertical when placed on the wall, the break away tabs are well executed. Hard to believe, or get excited about a simple Gang Box, but I am impressed. These probably cost more, but well, well worth the extra chump change. I strongly recommend these boxes, by this company. Plus made in Los Estados Unidos. I was only expecting one box, I know my buddies will be happy now.

          Just an outstanding new electrical single gang box, wish I had then forty years ago, can think of a lot of jobs where they would have been perfect. Love the ways they come all on one box not a bunch of different ones to carry on truck for use when you need them. Can use in the way most are used the nail on, then for limited space where nail on is not the box you need the attach to front of the stud. the for that adding a box inn an existing wall use screws and as you can see in picture can mount in normal horizontal or where you need the box laying down are screw holes in the bottom of the box.

          Easy to install and has a lot of space for the cables.

              Box works fine, large internal space for wiring a 3-way switch. I installed it in 'old work' (with exposed studs behind drywall) so had to break off the mounting flange, then needed to trim the surface with a sharp wood chisel. The nails are towards the rear of the box, and that gives more clearance from the back of the drywall.

                This is a multi-use product that can provide outstanding results under any circumstances; whether when new work is addressed or when new work results are needed in a finished room. Would recommend this product to anyone.

                    Easy to use - sturdy / just mount on a stud / either side - I used screws / that it will not become loose as people use with the switch or outlet - if you want it extra sturdy just add a cross brace between the studs
