It's built for it. The 4XSFSD3PT is a NEMA 4X enclosure in 304 stainless steel with a seamless poured in-place gasket, so it's rated against hose-directed water and corrosion. The #4 brushed finish is the standard stainless mill finish, no paint to chalk or peel. That combination is what you want for wastewater plants, food processing washdown areas, marine air, and chemical exposure.

No. The 4XSFSD3PT ships with no mounting provisions inside, meaning no back panel, no rails, no collar studs. You order the subpanel and any interior mounting hardware separately and size it to the 72 x 72 inch interior. Budget for that on the same order or the electrician shows up with nothing to land gear on.

It's a large double door design with a 3-point latching handle, so the door pulls tight top, center and bottom for even gasket compression across a 72 inch opening. The handle carries a key lock and padlock provision, so you can secure it with the key alone or add your own padlock for lockout or site security.

A double door gives you one continuous 72 inch wide by 72 inch high interior with no center post breaking up the back panel, so wide gear, long wireways, and horizontal bus runs land in one box. Two singles give you a divider you have to work around. The tradeoff is swing: both doors open across roughly 72 inches of face, so confirm your aisle clearance. A 3-point handle keeps the seal even across that span.

It carries UL 50, the standard for enclosures for electrical equipment, and it's manufactured in the US. For spec submittals, cite it as Eaton B-Line model 4XSFSD3PT, part number 727218-4XSFSD3PT.

You can, but any hole you cut has to be sealed back to 4X with a listed watertight hub or fitting, not a standard locknut and bushing. The enclosure ships with no mounting provisions and no factory conduit openings, so all penetrations are field work. Cutting 12 gauge 304 stainless calls for a hole saw rated for stainless or a hydraulic punch, and deburr and passivate the cut edge so you don't start corrosion on a box you bought specifically for corrosion resistance.

Eighteen inches back to front is the usable depth on the 4XSFSD3PT, measured door to rear wall before you subtract your subpanel thickness and standoffs. That's comfortable for control panels, PLC racks, VFDs and distribution gear, but deep-bodied breakers, large drives with rear heat sinks, or anything needing rear cable bending space can run past it. Measure your deepest component plus wire bend radius against 18 inches before you commit.
