Minerallac C3B – Frequently Asked Questions

1) Will the Minerallac C3B conduit hanger fit 1-1/2 inch EMT and 1-1/4 inch rigid conduit?
The C3B bolt-on hanger is sized for 1-1/2 inch EMT or 1-1/4 inch Rigid/IMC. Because EMT and rigid of the same trade size have different outside diameters, the same hanger body covers both: order by what you are actually hanging, not by the number printed on the coupling.
2) Does the Minerallac conduit hanger come with the bolt and nut, or do I buy those separately?
Bolt and nut are included with the hanger, so there is nothing extra to source for the clamping hardware. What is not included is the anchor or fastener that attaches it to the structure, that depends on your substrate (wood screw, self-drilling screw into steel, or a concrete anchor).
3) Can a Minerallac bolt-on conduit hanger be hung from 1/4 inch threaded rod?
Yes. The hanger is set up for 1/4 inch rod, so it drops straight onto 1/4-20 threaded rod for ceiling-suspended runs. For surface work the same hanger bolts flat to wood, steel, concrete or a structural component through its single mounting hole.
4) What trade sizes do Minerallac bolt-on conduit hangers come in?
Four sizes in the bolt-on family: 1-1/2 inch (C3B), 2-1/2 inch (C6B), 3 inch (C7B) and 4 inch (C9B). Same zinc-plated steel construction and bolt-on method across all four, so a crew can standardize one hanger style over a run that changes conduit size.
5) Is a zinc-plated steel conduit hanger okay outdoors or in a wet area?
The C3B is low-carbon cold-rolled steel with a zinc-plated finish, which is corrosion resistance intended for indoor installation conditions. For continuously wet, exterior, or washdown locations, step up to a hot-dip galvanized or stainless support instead of zinc plate.
6) Is the Minerallac C3B conduit hanger made in the USA for a Buy American job?
The C3B is manufactured in the United States, which is the detail that matters on federally funded and institutional work with domestic sourcing language in the spec.
7) Can I use this hanger on a concrete wall, or is it only for wood framing?
Both. Mounting is rated for component, wood, steel and concrete surfaces, so the same part anchors rigid conduit to a concrete wall or screws to wood blocking and steel framing. You supply the anchor suited to the substrate; the hanger's own bolt and nut are included.
8) Will a bolt-on conduit hanger look acceptable on exposed conduit in a finished space?
It is a silver zinc-plated finish, uniform from piece to piece, which is why it gets used on exposed runs in finished commercial areas. Property managers replacing a few hangers in an existing run will get a visual match to other zinc-plated supports.
