Steel City H4BD 1/2 3/4 – Frequently Asked Questions
1) What knockout sizes does the Steel City H4BD gang box come in?
Two knockout configurations: H4BD 1/2 3/4 covers 1/2 inch and 3/4 inch trade sizes, and H4BD 3/4 1 covers 3/4 inch and 1 inch. Pick the one that matches the conduit you are running into the box, since the knockouts are formed into the drawn steel body and cannot be changed in the field.
2) How many cubic inches is the H4BD 4-gang box, and will it take my conductor count?
110 cubic inches of volume in a 4-gang drawn steel body. That is the figure you use for NEC box-fill math, so count your conductors, devices, clamps and grounds against 110 cubic inches before you commit to it.
3) Is the Steel City H4BD a surface-mount box or does it go in the wall?
It is a surface mounted housing, so it lands on the face of the wall, deck or structure rather than being set between studs behind finished drywall. For exposed work in plants, garages, back-of-house and mechanical rooms that is what you want. If you need a box buried in a finished wall, this is the wrong style.
4) Is the Steel City H4BD UL listed for commercial and institutional work?
Yes. The H4BD carries UL E2969 and CSA 5043, so it is acceptable on both US and Canadian jobs where an inspector wants a listed box.
5) What is the difference between the Steel City H4BD gang box and the Kraloy FD PVC gang box?
They are built from different materials and serve different gang counts. The Steel City H4BD is a drawn steel surface-mounted housing with four outlets and 110 cubic inches of capacity, finished in silver, and it carries UL E2969 and CSA 5043. The Kraloy FD is a PVC 1-gang deep box supplied with a blank cover. If the layout calls for four devices in one steel housing, the H4BD covers it; for a single-gang nonmetallic box with a cover included, the Kraloy FD is the one to look at.
6) Can the H4BD gang box be mounted vertically?
The H4BD is specified for horizontal mounting, with the four device positions running side by side. If your layout calls for a vertical stack of devices, specify a box arranged for that orientation instead.
7) Should I use a steel gang box like the H4BD or a PVC one?
Steel is the usual call for exposed commercial and industrial work: the H4BD is a drawn steel 4-gang surface box with 110 cubic inches, listed under UL E2969 and CSA 5043. Where you are running nonmetallic conduit and want a nonmetallic system throughout, a PVC box such as the Kraloy FD Series 1-gang deep box is the other route, though that one is single gang and will not take four devices.
8) I only need one device at this location - is there a smaller alternative to the Steel City H4BD?
Yes. The H4BD is a four-outlet steel housing with 110 cubic inches of volume, which is more box than a single device needs. For a one-device point, the Kraloy FD is a 1-gang deep box in PVC and ships with a blank cover, so it suits a single-gang rough-in or a blanked-off junction point without carrying the four-gang footprint.
9) What is the H4BD box made of, and will it hold up in a shop or garage?
Steel, drawn rather than welded up from sheet, in a silver finish. A drawn steel body has no seams at the corners, which is why these are used for exposed industrial and MRO work where the box takes knocks. For wet or corrosive locations check the fitting and gasketing you pair with it.
10) Do I have to buy the H4BD gang box in a case?
The H4BD is packed with an outer quantity of 5, so cases come five boxes to a carton. Order in multiples of five if you want full cartons.
