Orbit Industries BMA-4 Box Mount Adapter Metal Stud

Product Description

The ORBIT INDUSTRIES BMA-4 is a box mount adapter designed to secure electrical boxes to metal stud framing using far side support. It is used in rough-in electrical work where a standard box bracket cannot attach directly to the near side of a stud. The adapter spans the stud cavity and locks the box in place, keeping it flush and stable for device installation. Electricians install this adapter during new construction or renovation work on metal stud walls. It accommodates 2.5-inch, 3.5-inch, and 4-inch metal stud sizes, making it usable across a range of commercial and residential framing profiles.

This adapter is suited for commercial and residential electrical rough-in work wherever metal stud framing is present. It is particularly useful in drywall partition walls where box placement must be set before the wall surface is closed. The far side support design allows the box to be anchored securely without requiring a stud flange on the installer's side. It is a common solution in office build-outs, multi-family construction, and any project using light-gauge metal framing.

Installation Notes

Installation is performed by a licensed electrician in accordance with the National Electrical Code (NEC). Power should be off and locked out before working in any energized panel or junction area nearby. Position the adapter across the metal stud opening and secure it before attaching the electrical box, following the manufacturer's mounting instructions. Do not force the adapter onto stud sizes outside the specified range, as this may compromise the structural hold.
