Topaz Lighting FS2MHDG – Frequently Asked Questions

1) What size conduit does the Topaz FS2MHDG box accept?
One 3/4 inch tapered NPT threaded hub. It's a single-hub FS box, so you get one threaded entry, sized for 3/4 inch rigid or IMC conduit. Threaded hubs mean you thread the conduit directly into the box; no locknuts or connectors needed at that entry.
2) Can I use this FS box with EMT?
No. The FS2MHDG is built for rigid and IMC conduit with threaded NPT connections. EMT is not threaded, so you would need an EMT-to-threaded adapter fitting to land it in this hub, or pick a box intended for EMT.
3) Is this FS box rated for outdoor or wet locations?
Wet location use is allowed, but only when the box is closed up with a compatible cover and neoprene gasket (Topaz FSFDCG). The box alone is not a wet location assembly. The malleable iron body with hot-dip galvanized coating is what makes it hold up outdoors and in corrosive spots.
4) What else do I need to order to finish the installation?
The box is a body only. Plan on a cover to suit the device or blank-off you need, plus the FSFDCG neoprene gasket if the location is wet. Grounding is handled at the box itself, since internal grounding screws are built in, so you land your equipment ground there.
5) Is a single-hub FS box the right one, or do I need a two-hub FS?
Single hub means one threaded entry only. Use the FS2MHDG at the end of a run: a device outlet, a splice point, or a pull point where conduit comes in from one direction. If conduit has to pass through, in one side and out the other, you want a through-feed FS body instead, not this one.
6) Why choose a malleable iron FS box over a die-cast aluminum one?
Malleable iron with a hot-dip galvanized finish is the choice where the box takes impact or sits in a corrosive, exposed environment. Aluminum bodies are lighter and easier to handle but don't offer the same impact strength. HDG also matters where the conduit run itself is galvanized rigid, so the whole system corrodes at the same rate.
7) Do I need to add a separate ground screw to this FS box?
No. Internal grounding screws come in the box, so the equipment ground can be landed directly inside without drilling and tapping. That matters on a galvanized rigid system where you're bonding the raceway at each body.
8) Does this Topaz FS box come in a case quantity or can I buy one?
The FS2MHDG is catalogued with a pack size of 100 units, which is the standard bulk carton for this fitting. That suits contractors and distributors stocking a full job's worth of 3/4 inch FS bodies rather than a one-off replacement.
9) Can I use this box as a pull point for conductors, or only for devices?
Both. The FS2MHDG gives you a threaded hub for the branch conduit run, an opening to make splices, and enough room to serve as a pull box for conductors. Cover it blank if there's no device going in it.
