Minerallac FBO23 – Frequently Asked Questions

1) Will the Minerallac FBO23 box support work on both 2-1/2 inch and 3-1/2 inch studs?
Yes. The FBO23 bracket is built to span either 2-1/2 inch or 3-1/2 inch studs, wood or metal, so one part covers both common interior framing widths on a job. That is useful on mixed framing where a 2-1/2 inch metal stud partition meets 2x4 wood framing and you do not want two separate brackets on the truck.
2) What size is the Minerallac FBO23 electrical box bracket?
The FBO23 measures 5.87 x 4.75 x 3.50 inches overall. Those three numbers are the bracket's footprint, so check your stud cavity depth and the space around the box location before you set it; it needs clear room between studs at the rough-in height.
3) Is the Minerallac FBO23 bracket okay in a damp or unconditioned space like a parking garage or warehouse?
The FBO23 is pre-galvanized steel, which gives it a zinc coating for corrosion resistance in typical interior and light industrial environments. Pre-galv is not the same as hot-dip after fabrication, so for direct weather exposure or wet, corrosive process areas you want a hot-dip or stainless support instead.
4) Is a box bracket like the FBO23 better than nailing the box straight to the stud?
Nail-on boxes are fine when the device lands right at a stud. A bar-type support like the FBO23 is what you use when the box has to sit between studs, when you need to adjust the box left or right to hit a layout dimension, or when you are working in metal stud framing where there is nothing to nail to. It carries the box off the framing on both sides rather than hanging it on one face.
5) Does the Minerallac FBO23 come with screws or the electrical box?
The FBO23 is the steel support bracket only. The device box and the fasteners that attach the box to the bracket and the bracket to the framing are ordered separately, so plan those into the same material pull.
6) Is the Minerallac FBO23 box support made in the USA for a Buy American job?
Country of origin on the FBO23 is the United States, which is what a federally funded or public agency project file usually needs on the submittal. The part is stamped steel construction.
7) What is the Minerallac part number for this box mounting bracket?
Order it as Minerallac FBO23. That is the manufacturer part number for the pre-galvanized steel box support sized 5.87 x 4.75 x 3.50.
8) What does the Minerallac FBO23 bracket look like once it is in the wall?
Plain silver steel finish, and it sits inside the stud cavity behind the drywall, so nothing shows once the wall is closed and the device plate goes on. Appearance is not a selection factor here.
