Choosing an enclosure for a control panel or a DIN rail assembly usually comes down to three questions: how much interior space you need, whether the box will live indoors or outdoors, and whether you want new condition or are open to a used unit. The four options here range from a compact 12-inch steel box to a large 36-inch cabinet, with listed prices from $40.00 to $169.00. No single choice is obviously right for every shop; the key is matching the enclosure to the environment and the amount of equipment you plan to mount.
For indoor panels, the Unity 12x12x6 Type 1 steel box is the most straightforward pick. For wall-mount duty outside, the Hualey carbon steel boxes cover that need. For a large control cabinet with a backplate and room for expansion, the used Saginaw 36x24x8 is the one to evaluate.

Saginaw SCE-36EL2408LP Electrical Enclosure Control Cabinet 36x24x8" Backplate
The largest option in this group is a 36x24x8-inch electrical enclosure control cabinet with a backplate, sold in used condition. If your control panel houses a lot of DIN rail-mounted breakers, contactors, or terminal blocks, this is the one that gives you room to breathe. It is rated for NEMA 3R, 12, and 4 environments, so it is positioned for a wider range of installations. The tradeoff is condition and price: it is the highest-priced unit in the comparison, and because it is used, you will want to look it over before making it part of your build. For a large cabinet, the included backplate is a practical plus.
Unity Type 1 Electrical Enclosure 12x12x6 Steel Control Box UL Listed 12" x 12
Unity's Type 1 electrical enclosure measures 12x12x6 inches and is a gray powder-coated steel box with a removable screw-on cover, made in the USA and identified as UL Listed in the title. It is in new open-box condition, which means the enclosure itself is unused but may show minor handling marks. The 12-inch square footprint works well for a compact control panel, junction box, or a small DIN rail assembly where you do not need outdoor protection. The limitation is environmental: Type 1 is for indoor use, so this should not be your pick for washdown, rain, or damp locations. If you want a U.S.-made indoor enclosure at the lower end of the price range, this is the straightforward option.
Steel Electrical Enclosure Wall Mount Junction Box Outdoor IP65 12/16/20/24
The Hualey steel electrical enclosure is an IP65-rated carbon steel box with a hinged cover and reinforced lock, suitable for indoor or outdoor use. The series name includes multiple size options, while the specified dimension for this option is 19.7 x 15.7 x 7.8 inches. That makes it a mid-size wall-mount junction box for factory, construction-site, mall, or courtyard applications. The reason to choose this one is the IP65 rating plus the wall-mount design, all at a moderate price. The limitation is that only one product dimension is tied to this particular entry, so if you need a different size within the series, the title alone does not pin down which of those sizes applies.
12/16/20/24" IP65 Steel Electrical Enclosure Wall Mount Junction Box Outdoor
This Hualey version is the second steel enclosure in the set, and its title puts the 12/16/20/24-inch size family first. The product dimension shown for this unit is 19.7 x 15.7 x 7.8 inches, and the material is carbon steel. It is listed as new and can be used indoors or outdoors. The strength of this pick is the clear series name if you are planning around a range of sizes. The limitation is that the series title covers multiple sizes, but the specified product dimension is one discrete size, so treat 19.7 x 15.7 x 7.8 inches as the concrete size for this unit.
Final recommendation by use case
If your control panel is a dense indoor assembly and you want a no-fuss steel box, the Unity Type 1 12x12x6 is the most balanced pick. If rain or dust is a concern and you need an outdoor enclosure, the Hualey outdoor wall-mount box gives you that protection without stepping up to a large cabinet. If the project needs serious interior volume, the used Saginaw SCE-36EL2408LP is the only option here that starts at that scale. And if you are shopping by size family, the Hualey size-flexible entry covers the range in its title.
