Choosing a 24x24 steel enclosure for a control panel or din rail setup comes down to more than face size. You're looking at two cuboid carbon steel boxes with the same 24-inch front, but their depths and prices sit at opposite ends: an 8-inch-deep box listed at USD 70.33 and a 12-inch-deep box listed at USD 139.99. The real question is whether you need the extra interior room, or whether the shallower, lower-priced unit gives you enough space to mount and wire your gear cleanly.
Quick verdict
If your components and wire bends fit within a modest interior depth, the 24x24x8 enclosure is the practical pick. If you need noticeably deeper clearance, the 24x24x12 enclosure is the one to buy. It is the deeper of the two, its door hardware is ready for a lockable install, and it leaves more room between the mounting surface and the door for bulkier layouts.

Where each product wins
The shallow-box side wins on price and footprint. It is the lower-priced option in this pairing, and its more compact body works when panel space is tight. It also keeps the overall build shallower, which can make mounting and routing easier in confined areas.
The deep-box side wins on clearance and door hardware. The extra depth gives you more room to organize wiring behind components, and the door setup is already part of the package.
Product notes
24x24x8" Industrial Steel Enclosure
The lower-priced member of this pair is a cuboid carbon steel enclosure with a white-gray finish. For a control panel layout that doesn't need a deep cavity, this box keeps the assembly compact and leaves more of the budget for breakers, terminals, and wire. The mounting plate is called out in the product title, so it is easy to plan the build around. The limitation is interior clearance: the listed inner depth is 7 inches, and once components are mounted on the backplate, you have to keep wiring and hardware inside that space. It is a good fit for straightforward layouts, but not for components that need a lot of depth behind the panel.
24x24x12" Carbon Steel Enclosure
The deeper member of this pair is a carbon steel enclosure with a powder-coated finish, and the added depth is the main reason to choose it. You get more room for components that sit farther off the mounting surface, and you can keep wire bends inside the box instead of forcing them into a thin cavity. The limitation is the price. This is the higher-priced box in the pairing, so if you don't need the extra depth, you are paying for space that will stay empty. It suits installations with deeper components or heavier wire bending.
Final choice by use case
If you want the lower-priced way to get a 24x24 footprint and your components fit in a shallow cavity, choose the shallow enclosure. If you need real depth for roomy wiring, choose the deeper enclosure. Both are cuboid carbon steel boxes with the same 24-inch face; the deciding factor is how much space sits behind the panel.
