XIUTE 6 Pack 1-Gang PVC Electrical Box
The XIUTE 6-pack offers a lightweight PVC solution ideal for metal stud installations. Its adjustable design simplifies alignment during installation, helping to classify and manage wires in an orderly fashion. At roughly 148 grams, these boxes are easy to handle on various wall types, reducing labor and construction costs. The 21 cu. in. capacity accommodates standard switches and outlets while maintaining a slim profile suitable for typical interior framing.
Key features include adjustable and lightweight construction for faster installs, home-application versatility, and notably low weight compared with metal boxes. This makes them suitable for projects where metal studs are present and a non-metallic box is preferred for ease of routing and corrosion resistance.
10-Pack Single Gang Electrical Box (Blue)
This blue PVC box is designed for New Work installations and comes in a 10-count package, providing 18 cu. in. of capacity per box. It features a straightforward installation with captive screws and positioning tabs to aid precise mounting, especially when anchoring into studs. The blue color helps identify it as a plastic, non-metallic option, which can be advantageous in certain wall assemblies where metal boxes are less desirable or where added corrosion resistance is beneficial.
Its four removable tabs support flexible wiring in and out of the box, aiding wiring aesthetics and efficiency. The design is optimized to accommodate standard switches and outlets, making it a reliable option for both residential and commercial applications where plastic boxes are suitable for metal stud framing.
XGGYA Old Work Box, Plastic 1-Gang
This old-work plastic junction box is designed for retrofit installations in existing walls. It uses built-in fixing ears and a rotatable buckle to secure the box, reducing the risk of dropping during mounting. The compact dimensions (4-1/3-inch length by 2-1/5-inch width by 2-3/4-inch depth) provide a balanced size that fits well with standard wall cavities while maintaining accessibility for wiring and devices. It is AWG-compatible and uses a snap-on connection to prevent loosening during use.
Ideal for upgrading older walls without extensive remodeling, this box supports straightforward wiring in and out and offers a longer service life in spaces where metal studs are present but plastic boxes are preferred for ease of installation and corrosion resistance.
Qlvily 8 Packs 4 x 2 Inch Metal Electrical Box
While this option is metal-based, it is relevant in discussions about plastic boxes for metal studs because it highlights how metal brackets and knockouts interact with stud framing. The box features seven 1/2-inch knockouts, a TS side-mount bracket, and durable iron construction to resist rust. This product can accompany plastic box installations in mixed-material projects, where metal brackets are used to reinforce mounting on metal studs and ensure strong mounting for devices.
The inclusion of robust brackets and multiple knockout options provides flexibility for routing and terminating conductors in tighter spaces often encountered around metal stud configurations.
Southwire Electrical Box for Lighting Fixture
This 1-gang box is designed for lighting fixtures and features a depth-adjust capability up to 22.5 cu in, with built-in wire clamps that aid fast, secure assembly. While not exclusively plastic, it demonstrates a broader approach to electrical boxes used with metal studs in lighting circuits. The flexibility for entering wires from both the top and bottom supports versatile installation in ceiling or wall-mounted fixtures, a common scenario in metal stud framing where space management is key.
(4 Pack) 4 x 2 Inch Metal Handy Electrical Box
This 4 x 2-inch metal handy box from Airmont Products provides durable steel construction with a 1-7/8-inch depth and ten 1/2-inch knockouts. It is a sturdy choice for use with metal studs in exposed conduit or surface-mounted installations. While metal, it serves as a reference point for comparing installation ease, space, and compatibility when plastic boxes are considered for metal stud walls.
SIGMA ENGINEERED SOLUTIONS 14250 Metal Electrical Box
This weatherproof 1-gang metal box is designed for outdoor or wet locations, featuring three 1/2-inch holes and NEMA 3R rating. It includes ground screws, closure plugs, mounting lugs, and self-tapping screws.

Buying Guide: Key Considerations For Plastic Boxes On Metal Studs
- Material compatibility: Plastic (PVC) boxes resist corrosion and are lighter than metal boxes, but ensure their wall thickness, mounting options, and knockout patterns suit your metal-stud framing and any associated conduits.
- Box capacity and depth: Choose a box with adequate cubic inches for the intended switches, outlets, and devices, while providing space for wire routing and connectors. Deeper boxes may simplify installation in tight metal stud bays.
- New work vs. old work: New-work plastic boxes typically include mounting tabs or nails for stud attachment, whereas old-work versions are designed to retrofit into existing walls with built-in fixing features. Consider which scenario matches your project.
- Mounting and bracing: Metal studs often require brackets or additional mounting supports. If using plastic boxes, verify that they can be securely anchored to metal studs and that any required brackets are compatible with the box design.
- Accessibility and safety: Weatherproof or outdoor-rated plastic boxes exist for exposed or wet locations, while standard options suit interior walls. For exterior or damp environments, consider UL/CSA listings and NEMA ratings where applicable.
- Code compliance: Verify adherence to local electrical codes and restrictions on box types, conductor fill, and mounting in metal stud walls. Plastic boxes must meet relevant standards for non-metallic electrical boxes in your jurisdiction.
- Installation ease: Look for features such as captive screws, fixed tabs, and removable knockouts which streamline wiring and reduce labor, particularly in busy or cluttered metal-stud installations.
- Durability and handling: While plastic boxes are easier to handle, consider the mechanical stresses of the installation, potential impact during wall finishing, and compatibility with devices and covers you plan to use.
