The 10106 SCG screw cover enclosure measures 10 inches high, 10 inches wide and 6 inches deep. That 6 inch depth is what usually decides these jobs, since it sets how much room you have behind the cover for splices, terminal blocks or a small contactor. Body weight is 10.9 lb.

Yes. The 10106 SCG carries a NEMA 3 rating, which covers outdoor use against windblown dust, rain and sleet, and the description also calls out NEMA 3R and 12. It is sealed with an oil-resistant gasket and gasketed cover screws, so it also holds up to dripping oil and coolant on a shop floor. Galvanized steel body, unfinished.

No. The 10106 SCG ships with no mounting provisions, so there are no factory feet, brackets or mounting holes in the back. It is a surface mount enclosure, which means you supply the mounting hardware or add a mounting foot kit, and you drill the back or use external feet yourself. Drilling the back of a NEMA 3 box will compromise the rating, so external feet are the usual route.

No knockouts. This is a blank galvanized steel enclosure, so you punch your own conduit entries where you need them. For an outdoor NEMA 3 install, use gasketed hubs or watertight fittings at every penetration, and keep entries on the sides or bottom rather than the top.

14 gauge galvanized steel. That is a heavier wall than the 16 gauge typically used on lighter-duty pull boxes, so the box keeps its shape when you punch conduit entries and can take the weight of a device panel inside. Finished weight is 10.9 lb.

Screw cover, like the 10106 SCG, is the right call where the box is opened rarely, such as a pull point, a splice box or a terminal junction. The cover comes fully off and takes two hands, which is a nuisance if you need routine access. If a technician opens it regularly for testing or resetting a device, a hinged cover enclosure is the better choice. The trade-off is that the screw cover with gasketed screws gives you a simpler, more uniform seal all the way around.

The 10106 SCG is built to UL 50, the standard covering enclosures for electrical equipment. It is made in the US.

It arrives unfinished galvanized, grey in appearance, with no paint topcoat. That suits mechanical rooms, roofs, parking structures and exterior walls. For a tenant-facing or architectural location, you would want a painted enclosure instead, or plan to prime and paint the galvanized surface yourself.
