4 in. H x 2 in. W x 1-7/8 in. D Steel Gray 1-Gang Drawn Handy Box with Ten 1/2 in. KO's and Raised Ground, 1-Pack

With a device installed, a single 12/2 with ground is acceptable.

Yes.

Why do you think they made the box? That answers your question!

1-7/8" depth

It is 1-5/8" (not including the cover plate) 1-7/8" (with the cover plate on)

The depth of the box is 1 3/4"

The covers mount to the receptacle, the receptacle mounts to electrical box. Yes GFCI receptacles can be used with this box.

Yes, we also offer GFCI cover model #862 which can also be used with this box.

No, a handy box GFCI cover is a little different than all the other covers you may be familiar with. The spacing of mounting holes in a handy box GFCI cover is the same as the device screws. One screw will pass through the cover and also secure the device to the box both above and below the device. This is why I generally try to avoid them and would rather use a 1900 box with a raised GFCI cover.

Yes. You can mount a GFCI in the box but I prefer larger boxes.

If your house has old 2-wire cable with no ground there is no ground and using a this box with a pigtail will not create a ground. If your house has a conduit system with metal conduit to connect the boxes then yes, you can use this box with a pigtail to ground your receptacles.

The use of pigtails is acceptable, and recommended for grounding metal boxes, to electrical systems.

Yes, attach it with concrete anchors and screws.

sure-if you anchor it properly. The wiring will be exposed to view [and abuse] , so use conduit. Unpainted EMT against concrete looks good in a work area. A plain steel switch plate/cover plate is also a good addition.

Absolutely, but if using it outdoors I would not use this product. Instead look for a "wet location" box, or something specifically made to be outdoors in the elements. If installing this in concrete, you will need to mark your holes and pre-drill for some tapcon or other concrete screws, then just screw the screws through the holes in the back, and run the rest of your conduit. Add some wires and an outlet, and you're done!

Yes! However, know that this box does not come with a ground screw, so you will need to purchase them separately.

The galvanized steel 8660, is suitable for surface mounted installations, on concrete and block walls, in indoor/dry locations.

Perfect interior application. Conduit is called for, as noted elsewhere.

Yes, this can be surface mounted on an indoor concrete wall for either a receptacle or a switch.

Yes, these days it seems all electrical components are compatible with each other. There are dimensional standards that are applied, across the board.

Yes, this box is intended for use as a convenience outlet, switch box or small junction box.

Yes, you can, handy box plates are available for a Decora switch or GFCI receptacle to fit this handy box, but Home Depot does not sell them individually. Other box stores and supply houses do however sell them individually.

This box weighs approximately 0.484 lbs.

I am just guessing that it weighs around 3 or 4 ounces.

The electric box weighs 0.484 lbs.
