Hammond Manufacturing C4XSC12124SS N4X SCREW COVER - 12X12X4 - SS - 12 x 12 x 4

The C4XSC12124SS measures 12 inches high by 12 inches wide by 4 inches deep. That 4 inch depth is the limiting number for most jobs: once you account for the screw cover and gasket, deep contactors or DIN rail stacks with tall breakers will crowd it. Plan the backplate layout against the 4 inch dimension before you commit.

Yes, that is exactly what the Type 4X rating is for, and the C4XSC12124SS is built in stainless steel to back it up. 4X adds corrosion resistance to the watertight, dusttight, hosedown protection of Type 4, so it suits food plants, wet process areas, car washes and salt air exposure where a painted carbon steel box would rust at the seams and screw holes.

No. The Type 4X screw cover is supplied with no holes, and that is deliberate: any factory knockout would break the watertight, corrosion-resistant seal the 4X rating depends on. Drill or punch your own entries and use 4X-rated stainless or listed watertight hub fittings with sealing gaskets. Keep penetrations out of the top surface wherever the layout allows.

A screw cover like the C4XSC12124SS is the right call where the box is a terminal or junction point you open rarely: the cover comes off completely, giving unobstructed access to the whole 12 x 12 interior for pulling and landing conductors. If an operator or technician has to get inside routinely, or the box sits where a loose cover could drop, choose a hinged continuous hinge or clamped cover enclosure instead so the cover stays captive.

Hammond's C4XSC12124SS is both RoHS and REACH compliant, and it is USMCA compliant with Canada as the country of origin. That combination matters on government, healthcare and institutional purchase orders that carry domestic-content or trade-agreement clauses, and on specs with restricted substance language.

Order it as Hammond Manufacturing C4XSC12124SS. The number reads out as C4X (Type 4X), SC (screw cover), then 12-12-4 for the 12 x 12 x 4 dimensions and SS for stainless steel. Distributors cross-referencing a bill of material should match on that full string, since the same size exists in other cover styles and materials under different suffixes.

12 lbs. Light enough for one person to hold while setting it, but heavy enough that you should not hang it on drywall anchors alone. Into stud, strut, or unistrut with through-bolts for a wall mount, and keep in mind the loaded weight once the backplate and devices go in.

Treat the backplate as a separate line item. Hammond supplies the C4XSC12124SS as the enclosure body and screw cover; mounting panels for the 12 x 12 interior are ordered to match the box size. If you are landing components rather than just splicing conductors, add the panel to the order so the box is not sitting on a shelf waiting for one.
