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.
