Best Electrical Boxes for Metal Studs: Five Options for Secure Installation
The best electrical boxes for metal studs have a mounting bracket designed to attach to framing, or are paired with a compatible bracket. The RACO 8235 is a strong choice for a square box with a stud bracket; the Airmont handy box suits single-gang device installations; and the Tellegloww pack is for buyers who already have compatible square boxes and need mounting brackets. Compare box style, depth, knockouts, and included mounting hardware before choosing.

OHLECTRIC 4-Square Welded Electrical Box
This 4-inch square box is best for installations that need a sturdy steel enclosure with an included flush-mount bracket. The product is made from 16-gauge galvanized steel and uses a bracket designed to attach to the flat side of a stud. That mounting arrangement makes it relevant to metal-stud work, though installers should confirm the bracket’s fit with their specific framing and wall assembly.
Its listed openings include two 1/2-inch knockouts, one MKO, and four loom pryouts, offering several wiring-entry options. Choose this box when a square format and multiple knockout types are useful. A limitation is that the listed knockout selection may not suit every conduit or cable plan, so check entry requirements before installation.
RACO 8235 Square Box With Stud Bracket
The RACO 8235 is best for buyers seeking a 4-inch square box with a bracket intended for wood or metal studs. Its flush TS-style bracket is designed to enclose wiring, switches, receptacles, or lighting fixtures. The box is 2-1/8 inches deep and has a welded construction made from 1/16-inch pre-galvanized steel.
Eight 1/2-inch side knockouts and five TKO knockouts provide entry choices for different wiring layouts. Combination screw heads are listed as a feature for installation. Choose this model when the box needs to serve several device or fixture purposes. Its square format may be less suitable than a handy box where a compact single-gang enclosure is specifically required.
Airmont Single-Gang Handy Box
This 4-by-2-inch handy box is best for a single-gang installation where a built-in mounting bracket can simplify attachment to framing. The integrated TS bracket is described as mounting directly to metal or wood studs. Its 1-7/8-inch depth and stated 13-cubic-inch capacity match the standard handy-box dimensions described in the product information.
A preset 1/2-inch setback is intended to help align devices with finished walls. Choose this option when compact size, a single-gang format, and an integrated bracket are priorities. It is not the best choice when the project calls for a larger square junction box or more interior capacity than the listed 13 cubic inches.
Tellegloww 100-Pack Box Mounting Brackets
These brackets are best for contractors or larger projects that need mounting hardware for compatible 4-inch or 4-11/16-inch square boxes. The product includes 100 galvanized-steel brackets with support legs. The listed design accommodates framing depths of 2-1/2, 3-1/2, and 3-5/8 inches and is described for attachment to wood or metal framing.
The support legs are intended to reduce box wobble and help maintain a stable position. Choose this pack when the boxes are purchased separately and the specified bracket dimensions match the framing. These are mounting brackets, not complete electrical boxes; confirm box compatibility and framing dimensions before ordering.
Fasmov 20-Pack Galvanized Handy Boxes
This 20-pack is best for projects requiring multiple 1-gang handy boxes. Each box measures 4 by 2 inches, is 1-7/8 inches deep, and has a stated 13-cubic-inch capacity. The product information describes 1/16-inch pre-galvanized steel construction and ten 1/2-inch knockouts per box: six on the sides, two on the ends, and two on the top or bottom.
Choose this pack when quantity and multiple knockout locations matter. The product listing says screw accessories are not included, so plan for the required mounting hardware separately. The provided features do not specify an integrated metal-stud bracket; verify how each box will attach to the framing before selecting it for a metal-stud installation.
Buying Guide: How To Choose Electrical Boxes For Metal Studs
Does the box include a metal-stud bracket?
Check whether the bracket is built into the box, supplied separately, or not specified. The RACO and Airmont listings describe stud brackets, while Tellegloww sells brackets separately. The Fasmov listing does not describe an included mounting bracket. Confirm the hardware and attachment method before purchasing.
Should you choose a square box or a handy box?
A 4-inch square box can suit junction, wiring, switch, receptacle, or lighting applications, depending on the model and installation. A 4-by-2-inch handy box is a compact single-gang option. Compare the box’s dimensions and stated capacity with the device and wiring needs rather than assuming the formats are interchangeable.
How do depth and knockouts affect the choice?
Deeper boxes may offer a different amount of working space, but compare the actual listed dimensions and capacity. Knockout size, location, and type determine which wiring entries are available. Match these details to the planned wiring route and installation requirements.
What should you verify for metal framing?
Check bracket dimensions, framing depth, mounting position, and alignment with the finished wall. Product descriptions may mention metal studs but do not establish suitability for every stud profile or wall assembly. Follow applicable electrical codes and the installation instructions for the selected box and bracket.
Frequently Asked Questions
Can a standard electrical box attach directly to a metal stud?
Only if its mounting design and hardware support that installation. Look for an included stud bracket or select a compatible bracket separately, and verify fit for the specific framing.
Are electrical boxes and mounting brackets the same product?
No. A box encloses electrical wiring or devices; a mounting bracket supports the box at the framing. The Tellegloww product is a bracket pack, not a box.
What is a handy electrical box used for?
A handy box is a compact, typically single-gang enclosure. The Airmont and Fasmov models listed here are 4 by 2 inches and have a stated 13-cubic-inch capacity.
Do all boxes in this selection include mounting screws?
The provided product details do not establish that all models include screws. The Fasmov listing specifically says screw accessories are not included; check each product’s package details.
