Allied Moulded ALMSB-2 – Frequently Asked Questions

1) How many devices does the Allied Moulded SB-2 box hold?
The SB-2 is a 2-gang box, so it takes two straight blade devices side by side, any mix of switches and receptacles. If you only need a single switch or duplex receptacle, this is one gang too many; if you are ganging three or more devices, you need a larger box.
2) Is 42 cubic inches enough volume for two devices and 12 gauge wiring?
The SB-2 gives you 42 cubic inches of interior volume, which is generous for a 2-gang box. Box fill still has to be calculated per the NEC for your actual conductor count, device yokes, clamps and grounds, but 42 cubic inches leaves real working room for wire nuts and folding conductors behind two devices rather than fighting the box on trim-out.
3) What does the Sliderbox adjustable feature actually do on the SB-2?
It lets you adjust the box depth on site after rough-in, so the device face can be brought flush with the finished wall surface. That matters when drywall thickness changes, when you are furring out a wall, or when tile or panelling goes over the rock. Without it you are shimming devices or living with a recessed plate.
4) What are the dimensions of the SB-2 switch box?
The SB-2 measures 4 x 3-3/4 x 3-9/16 inches. That footprint drops into standard framing with a nominal 3-1/2 inch stud depth, so check your cavity if you are working in a 2x3 or furred wall where the box depth could run past the back of the framing.
5) Is the SB-2 a metal or plastic box, and does it need a grounding pigtail?
It is a thermoplastic box, non-conductive and non-metallic. Because the enclosure itself is not part of the grounding path, the equipment grounding conductors get joined and carried to the device ground screw rather than bonded to the box, which is normal practice with nonmetallic boxes.
6) Can I use the SB-2 for a remodel, or is it new-construction only?
It suits both. Allied Moulded lists the SB-2 for new construction wall wiring and for renovation and remodel electrical work, with the adjustable design helping align the device to whatever finished surface you end up with. Where the framing is already closed up and you are cutting into finished drywall, a retrofit old-work box with wing clamps is the better choice, since this box is a rough-in style box.
7) What is the Allied Moulded part number for the 2-gang Sliderbox?
Order it as SB-2. That is the manufacturer part number for the 2-gang thermoplastic Sliderbox switch box, and it is the only model under that designation, so there are no finish or depth variants to choose between.
8) Will a standard two-gang cover plate fit the SB-2?
Yes. The SB-2 is a 2-gang box built for straight blade devices, so standard 2-gang device plates for duplex receptacles or toggle switches line up on the normal device mounting centers. Pick the plate to match the devices you install, not the box.
