B-Line Eaton series JIC panel enclosure, 17.58" height, 8.34" length, 15.96" width, 4X, Hinged cover, SDF enclosure, Wall mount, Medium single door,

The Eaton B-Line 16148-SDF carries a NEMA 4X rating, so it handles hosedown, windblown dust and rain, and corrosive environments. The fiberglass body and stainless screws are what earn the X (corrosion resistance), which is why it gets specified for food processing, wastewater plants, car washes and coastal exteriors instead of a painted steel box.

Outside dimensions are 17.58 inches high, 15.96 inches wide, and 8.34 inches deep. Those are external figures, so subtract wall thickness and allow for the poured in-place gasket flange when you lay out a back panel or size a breaker, contactor, or small drive. The 8.34 inch depth is generous enough for terminal blocks and a compact VFD, but check door-mounted device clearance against the hinged cover swing.

It is a wall mount enclosure, but the external mounting feet are an optional item, not part of the box. Order the feet separately if you are standing it off a wall or a strut rack. Mounting through the inside of a 4X enclosure defeats the rating, so external feet are the correct way to hang it and keep the seal intact.

No back panel is included. The 16148-SDF ships as the fiberglass enclosure with its hinged cover, seamless poured in-place gasket, and stainless screws. Budget a separate mounting panel plus the optional external feet to finish the install.

Fiberglass is the call where corrosion or chemicals are the problem: chlorine rooms, fertilizer and grain handling, wastewater, coastal and marine exposure. That is what the 4X rating covers on the 16148-SDF. Painted steel is cheaper and stiffer for dry indoor machine rooms but it rusts once the finish is nicked. Steel also grounds through the enclosure; fiberglass is non-conductive, so plan on a bonded ground bar inside.

The 16148-SDF is built to UL 50 for enclosures and is made in the US. That combination is usually what a government, healthcare, or education procurement spec is looking for on domestic-content and listing requirements.

The cover is a hinged, screw-secured design using stainless screws, so it opens on hinges and closes down onto the gasket with hardware rather than a latch. There is no lock or padlock hasp supplied with the 16148-SDF. If the panel needs to be secured against tampering, plan for a separate locking provision.

11.5 pounds empty. That is light enough for one person to hold in place and fasten off, which is a real advantage over a comparable steel 4X box of the same size when you are mounting on a pole or an awkward exterior wall. Weight will climb once a back panel and devices go in.

It comes grey and unfinished, which is the standard molded fiberglass appearance for this SDF line. No paint or coating is applied. Keep in mind that drilling or modifying the enclosure, and any field finishing, is on you with respect to maintaining the 4X seal.
