Electrical Box Mounting Brackets

Electrical Box Mounting Brackets secure device and junction boxes to framing and masonry so outlets, switches, and data ports sit flush, solid, and code-compliant. Designed for residential and commercial installs, these supports speed rough-in, improve alignment, and reduce callbacks by keeping boxes at the correct depth through drywall, tile, or paneling.

Popular types include:
- New-work stud brackets: Nail-on or screw-on for wood or metal studs, with fixed or adjustable depth stops to match 1/2-inch or 5/8-inch wallboard.
- Bar hanger brackets: Expandable bars that span between studs, perfect for irregular stud spacing or multi-gang layouts.
- Retrofit/old-work brackets: Secure cut-in boxes to existing walls without opening large sections.
- Low-voltage mounting brackets and mud/plaster rings: Provide trim, depth control, and clean cutout edges for comms, AV, and data.
- Square box supports and gangable brackets: Keep 4-inch and 4-11/16-inch boxes rigid and aligned for device banks.

Most brackets are galvanized or zinc-coated steel for rigidity and corrosion resistance, with options for plastic low-voltage frames. Look for UL/CSA listings, pre-marked measurement tabs, and integrated guides that set consistent device height and spacing. Rigid mounting minimizes device wobble, improves faceplate fit, and supports heavier switches, GFCIs, and dimmers.

Tips for choosing and installing:
- Match the bracket to the stud type (wood or 20–25 gauge steel), box size (single, double, 4-inch square), and wall finish thickness, including tile or paneling.
- Use adjustable depth brackets to hit a flush finish and meet NEC requirements for box setback and extensions.
- For steel studs, use self-tapping screws; for masonry, pair brackets with appropriate anchors.
- Plan multi-gang runs with bar hangers to keep spacing and level consistent across devices.
- De-energize circuits, confirm box fill, and verify listing and load ratings.

Shop by gang count, adjustability, material, stud spacing, and compatibility with switch, outlet, junction, or low-voltage boxes to streamline your next rough-in or retrofit.
