Milbank 444-SC1 – Frequently Asked Questions

1) What should I use instead of the Milbank 444-SC1 if the junction box is going outdoors or getting washed down?
The Milbank 444-SC1 carries a NEMA 1 rating, which covers general-purpose indoor use only. For a wet, outdoor, or washdown location, step to the Rittal 80181 JB Series hinged-cover junction box, which is rated IP66/NEMA 4X. The hinged cover on the Rittal also means the lid stays captive when you open it, rather than coming off as a separate screw-on piece.
2) Is there a non-metallic alternative to the Milbank 444-SC1 screw cover junction box?
Yes. The Milbank 444-SC1 is a steel box with a polyester powder-coated finish. If you want a non-metallic enclosure for a corrosive or damp-prone area, the Carlon E987R is a polycarbonate screw-cover junction box measuring 6 inches by 6 inches by 4 inches, and the Cantex E983G family is non-metallic PVC. Both avoid the grounding and corrosion considerations that come with a steel body, though the Carlon is a larger footprint than the 4 by 4 by 4 inch Milbank.
3) What size is the Milbank 444-SC1 junction box inside?
It is a 4 x 4 x 4 inch steel box, so it is a full 4 inch deep cube rather than a shallow 4 inch square box. That extra depth is what makes it workable as a splice or pull point for several conduit runs instead of just a device box.
4) Is a screw cover box better than a hinged cover for a junction I need to open often?
A screw cover like the 444-SC1 stays fully closed in service and comes off with its screws when you need access, which suits a splice or pull point you touch at install and then rarely again. If the box is a terminal point you open routinely, a hinged cover saves you chasing loose screws, and the Rittal 80181 JB Series is a hinged-cover junction box.
5) Should I use a steel junction box or a PVC one for an indoor splice?
Steel, like the Milbank 444-SC1, takes impact and supports conduit better and bonds as part of a metallic raceway system. Non-metallic boxes are the choice where you want no corrosion path or no bonding of the enclosure: ZenSupply carries the Carlon E987R polycarbonate screw-cover box at 6 x 6 x 4 inches and the Cantex E983G non-metallic PVC junction box family.
6) I need more room than a 4x4x4 box gives me for conductor fill. What is the next step up?
If the 444-SC1's 4 x 4 x 4 inch volume won't take your conductor count, step to a larger screw-cover box such as the Carlon E987R at 6 x 6 x 4 inches. Going the other direction, for a shallower square box the Orbit D4SB series is a 1-1/2 inch deep 4 inch square box in drawn steel, sold 100 to a pack.
7) What is the closest equivalent to the Milbank 444-SC1 in a 4-inch square steel box?
Among 4-inch square steel boxes, the Orbit 4SDB Series square deep box is welded steel with 1-inch knockouts, and the Orbit D4SB Series is a 1-1/2 inch deep drawn-steel 4-inch square box sold in packs of 100. The Milbank 444-SC1 differs in depth and cover style: it is a 4 by 4 by 4 inch enclosure with a removable screw cover, where the Orbit boxes are shallower device-style squares typically covered with a separate 4-inch square plate.
8) I need a junction box with a knockout and cover already included - does the Milbank 444-SC1 come that way, or is there a simpler option?
The Milbank 444-SC1 ships as a screw cover enclosure, so the cover is part of the box. If you want a smaller non-metallic unit that arrives with both a knockout and cover, the Cantex 5133690 is a 4-1/8 inch junction box supplied with a 1/2 inch knockout and a cover. The Milbank is the steel choice of the two and is finished in ANSI 61 Gray powder coat for electrical room appearance.
9) Can I use an Orbit D4SB square box in place of a Milbank 444-SC1 as a conduit pull point?
They are not interchangeable for the same job. The Orbit D4SB is a 1-1/2 inch deep drawn-steel 4-inch square box, so it offers far less interior volume for conductor bending space than the 4-inch deep Milbank 444-SC1, which is sized to serve as a pull box, junction point, or splice enclosure within conduit and raceway systems. The D4SB is also sold in packs of 100 for device and fixture work, while the 444-SC1 is a single screw cover enclosure.
10) If I need more room than the Milbank 444-SC1 for splices, what larger screw-cover box is available?
The Milbank 444-SC1 is 4 inches by 4 inches by 4 inches. For more splice room in the same screw-cover style, the Carlon E987R measures 6 inches by 6 inches by 4 inches. The trade-off is material: the Carlon body is polycarbonate, while the Milbank is powder-coated steel.
11) Will the gray finish on the Milbank 444-SC1 match the other enclosures in my electrical room?
The finish is ANSI 61 Gray polyester powder coat, the standard gray used across most switchgear, panelboards, and industrial enclosures, so it lines up visually with the rest of a typical electrical room. The powder coat also gives the steel body corrosion resistance for indoor service.
12) What part number do I order for the Milbank 4x4x4 screw cover junction box?
Order Milbank 444-SC1. That is the single model for this box, so there are no finish or size options to specify at the order stage: the 4 x 4 x 4 inch steel body in ANSI 61 Gray is what ships.
