Hammond Manufacturing HJ443HLP – Frequently Asked Questions

1) Can the Hammond HJ443HLP junction box be mounted outdoors in the rain?
Yes. The HJ443HLP carries Type 3R and Type 4 ratings, so it is built for outdoor use against rain, sleet and hose-directed water, and it is rated IP66 for dust-tight protection and powerful water jets from any direction. Type 12 and 13 are also on the rating list, which covers indoor dust, drips and oil in a plant environment. The shell is mild steel, so in a chronically wet or washdown-chemical location a stainless or non-metallic box is the better long-term choice.
2) What are the actual box dimensions on the Hammond HJ443HLP 4x4x3?
Height 4 inches, width 4 inches, depth 3 inches. That 3 inch depth is the number to check first: it sets how much room you have behind the cover for terminal blocks, a small relay or wire bends. Wire fills with several large conductors and a splice get tight fast in a 3 inch deep box.
3) Does the Hammond HJ443HLP come with a back panel for mounting components?
No, it ships as the enclosure with hinged cover. A panel is offered for it but sold separately, so if you are landing terminal strips, a DIN rail or a small power supply inside, add the matching panel to the order or plan to drill and stand off your own.
4) Does this Hammond junction box come with knockouts, or do I have to drill my own conduit holes?
It comes without holes. A Type 4 and IP66 enclosure cannot ship with knockouts and still hold its seal, so you punch or drill your own openings where you need them and use watertight hubs or sealing-ring connectors. Any hole made in the field is only as good as the fitting you close it with, and an unrated connector drops the Type 4 rating at that point.
5) Is the Hammond HJ443HLP junction box UL and CSA listed for a commercial inspection?
It is listed to both. The UL file is E65324 and the CSA certification is LR21001, and CE is on the standards list as well. Those file numbers are what an AHJ or a submittal package will want to see against the Type 4 rating.
6) Why choose a hinged cover box instead of a screw-on lift-off cover?
The hinge matters where you open the box more than once. On a screw cover, the lid and all its screws come free in your hand every time, which is awkward on a wall or a pole and easy to drop into a machine. The HJ443HLP's hinged cover swings clear and stays attached for wiring, troubleshooting and inspection. For a splice you make once and never touch again, a screw cover is fine and usually cheaper.
7) Is a NEMA 4 steel box the right call for a food plant or washdown area?
Type 4 and IP66 handle the water, and Type 12 and 13 cover dust and oil, so the HJ443HLP suits control and junction duty in processing and manufacturing spaces. The limit is the material: mild steel is painted carbon steel, not stainless, so in a caustic washdown or a direct food-contact zone where sanitizers hit the box daily, specify a Type 4X stainless enclosure instead. Type 4 is watertight; it is not the corrosion-resistant rating.
8) What is the exact part number to order this Hammond 4x4x3 hinged junction box?
Hammond Manufacturing model HJ443HLP. One model covers the size, so there is no finish or hand to specify; the only add-on decision is whether you also need the separately sold mounting panel.
9) How heavy is the Hammond HJ443HLP and can I mount it to drywall or a strut?
Two pounds empty. At that weight the box itself is easy to hang on strut, a machine frame or a wall, and the steel body takes through-holes or external mounting feet. Add the weight of whatever you put inside plus the pull of the conduit runs when you size the anchors; conduit entering the sides usually carries more load than the box does.
10) Does the Hammond HJ443HLP meet RoHS and REACH for a spec that requires it?
Yes on both, and it is USMCA compliant with Canada as the country of origin. That combination covers most institutional and government procurement checklists that ask for material restriction and trade origin documentation on electrical enclosures.
