Minerallac FBO234 Electrical Box Mounting Bracket, Pre-Galvanized Steel Stud Support

The Minerallac FBO234 is a stamped electrical box mounting bracket engineered to securely support electrical boxes on 2-1/2", 3-1/2" and 4" wood or metal studs. Built from pre-galvanized steel for corrosion resistance and long-term durability, this box support bracket is designed for electricians and contractors who need a reliable, code-friendly way to mount electrical boxes to standard framing during new construction or remodel work. Its stamped steel construction and silver pre-galvanized finish provide a strong, rigid mounting platform that helps ensure electrical boxes stay firmly positioned at the correct depth and location within the wall cavity, reducing callbacks and rework on the jobsite. Measuring approximately 5.68 x 4.75 x 4.00 inches, the FBO234 is compact enough to fit efficiently into standard stud bays while still delivering the rigidity needed to hold an electrical box securely in place through rough-in, insulation, and drywall installation. Electrical contractors value brackets like the FBO234 because a single part number can cover multiple common stud widths, simplifying material lists and reducing the number of SKUs that need to be stocked on the truck or in the warehouse. This kind of multi-width compatibility is especially useful on mixed-framing jobsites where crews may encounter both 2-1/2" and 3-1/2" or 4" studs within the same project, allowing electricians to standardize their rough-in hardware without carrying redundant part numbers.

Key Features

  • Multi-Stud Compatibility: Fits 2-1/2", 3-1/2" and 4" wood or metal studs, giving installers flexibility across common residential and commercial framing widths without needing multiple bracket types on hand.
  • Durable Construction: Manufactured from pre-galvanized steel that resists rust and corrosion, supporting long-term reliability in interior wall and ceiling applications.
  • Stamped Steel Build: Stamped construction delivers a rigid, consistent mounting surface that keeps electrical boxes stable and properly aligned once installed.
  • Finish: Pre-galvanized silver finish provides a clean, corrosion-resistant appearance suited for exposed or concealed installations.
  • Compact Footprint: Sized at approximately 5.68 x 4.75 x 4.00 inches, the bracket installs quickly in tight stud bays while still providing solid support for a standard electrical box.
  • Made in the USA: Manufactured in the United States, offering electricians a domestically produced component for their rough-in material lists.

Minerallac FBO234 – Frequently Asked Questions

1) What stud widths does the Minerallac FBO234 box bracket fit?
The FBO234 bracket mounts electrical boxes on 2-1/2 inch, 3-1/2 inch and 4 inch studs. One part number covers all three, so a crew hitting both 2-1/2 inch metal studs and 3-1/2 inch wood framing on the same job only needs the one bracket on the truck.
2) Will the Minerallac FBO234 bracket work on metal studs, or is it only for wood framing?
Both. The FBO234 is rated for wood or metal studs in the 2-1/2, 3-1/2 and 4 inch widths, which is why it shows up on residential wood-frame rough-in and metal-stud commercial buildouts alike.
3) Is the Minerallac FBO234 box support galvanized, and will it hold up in a damp wall cavity?
It's stamped from pre-galvanized steel with a silver finish, so the zinc coating is on the sheet before forming. That gives corrosion resistance for interior wall and ceiling work, concealed or exposed. It is specified for interior applications, not weather-exposed exterior use.
4) Is the Minerallac FBO234 made in the USA for domestic-content jobs?
Yes. Country of origin on the FBO234 is the United States, which matters on federally funded and Buy American spec work where rough-in hardware has to be documented as domestic.
5) What is the Minerallac FBO234 actually for, and when would I use a different kind of box support?
The FBO234 is a stamped box support bracket: it spans or attaches to framing and carries an electrical box at the correct depth and location in the wall cavity. Use it when you have a stud at 2-1/2, 3-1/2 or 4 inches to work from. If the box has to land in the middle of a bay with no adjacent framing to pick up, or you're hanging a box from a ceiling grid or threaded rod, that is a different support type, not this bracket.
6) What is the Minerallac part number and MPN for this box mounting bracket?
Order it as Minerallac FBO234. That is both the model designation and the manufacturer part number, so it's the number to put on a submittal or a counter order.
