When you're picking a wall-mount electrical enclosure for a control panel, DIN-rail wiring, or an outdoor junction point, the decision usually narrows to price and interior room: how much space do you need for terminations and how much are you willing to spend? These two zivici boxes keep the comparison straightforward because both are carbon-steel IP65 junction boxes rated for indoor and outdoor use. The practical differences sit in the listed price, the size range named in the product title, and the dimensions of the specific unit described. For most panel work, the choice comes down to how much growth you expect inside the box and whether the smaller footprint saves you enough to matter.
Quick verdict
If you want the lower listed price, the 12'' 16'' 20'' model is the pick. If you'd rather have a larger listed unit and a product name that extends further, the 12" 16" 20" 24" model is the one to budget for.
Price and size comparison
| Feature | 12'' 16'' 20'' enclosure | 12" 16" 20" 24" enclosure |
|---|---|---|
| Listed price | USD 42.99 | USD 53.99 |
| Price bar | ||
| Size range in name | 12, 16, and 20 inch | 12, 16, 20, and 24 inch |
| Listed unit | 16 x 12 x 6 inches | 500 x 300 x 205 mm |
| Material | Carbon Steel | Carbon Steel |
| Model | SPT | SPT |
Both listings share the same brand, model number, material, and indoor/outdoor IP65 positioning, so the practical differences come down to the listed price and the size of the unit each listing describes.
Where each enclosure wins
The 12'' 16'' 20'' model wins on listed price. It also describes a compact unit, which is helpful when you already know exactly how much back-box space your wiring needs.
The 12" 16" 20" 24" model wins on the size range named in its title and the larger unit described. That extra length and depth matters when you're fitting more wiring or bulkier components and want room to work.
12'' 16'' 20'' Steel Electrical Enclosure IP65 Wall Mount Junction Box Outdoor
This is the lower-priced of the two zivici listings and the one that states a silver finish. The unit shown is 16 x 12 x 6 inches, so it suits a compact wiring layout such as a single circuit or a small termination point. The decision comes down to footprint and budget. The limitation is that footprint: the other listing describes a larger unit that is longer and deeper, so this box fits where space is tighter or you want to spend less.
12" 16" 20" 24"Steel Electrical Enclosure IP65 Wall Mount Junction Box Outdoor
This is the higher-priced listing, and its product name covers a size range that reaches a 24-inch option. The listed unit measures 500 x 300 x 205 mm, giving you noticeably more room than the other box. That's a meaningful difference if you're landing multiple circuits, splices, or DIN-rail mounted components. It's the listing to pick when you may need to move toward the larger end of the range. The trade-off is straightforward: it carries the higher listed price of the pair.
Final choice by use case
For a compact enclosure with a stated silver finish at the lower listed price, go with the 12'' 16'' 20'' model at USD 42.99. For a larger listed unit and a product-name range that extends further, the 12" 16" 20" 24" model at USD 53.99 is the one to choose.
