I'm out in Chicago, and we are required to pipe in everything with conduit and use metal boxes.
For vertical 2 gang outlets, we use normally a 4 inch box with side mounting to a stud and two mud rings (one for each gang). Image attached.
I'm trying to figure out (without ripping apart my house), how all the outlets in my kitchen are horizontal as the mounting flanges I've seen on metal boxes are vertical.
I've used the "old work" boxes with drywall clips and ears to put in a switch or outlet (so you can mount them vertical or horizontal as needed), but when my house was roughed in all of the 1 gang outlets are horizontal.
What sort of metal box is used for rough in that is installed horizontally, like the pictured horizontal outlet?
Best Answer
Sideways mud rings
I'm fairly sure that what your installers did to get the horizontal receptacle effect was to take a 4S (4" square) box (or another square box) and then mount a matching 1-gang mud ring on the square box so the 1-gang opening in the mud ring is horizontal, not vertical.
