XGGYA Old Work Box for Switches
The XGGYA box is designed for easy retrofit into existing walls. Its built-in fixing ears and rotatable buckle help prevent failures once installed, making it a good choice for renovating spaces where new holes are not desirable. Best for homeowners tackling one-off new sockets in finished walls, it supports common AWG ranges and provides a snug fit to reduce movement after wiring. A potential limitation is its relatively compact depth, which may require careful device selection for deeper switches or GFCIs.
ANKYLHUA 10-Pack New Work Box 1 Gang
This 10-pack of 1-gang new work boxes is sized for 57x71x93mm (about 2.24×2.79×3.66 inches) with 18 cu in capacity. It features captive screws and positioning tabs to simplify mounting, plus removable tabs for easy wiring in and out. It’s a solid value for installations where multiple boxes are needed, and its blue color helps identify new-work applications. A caveat is that some users may prefer deeper boxes for larger devices or more complex wiring layouts.
Airmont Products Outlet Box Kit
This kit combines a 4×2″ utility box, a toggle switch cover, a 15A outlet, copper grounding wire, and a 1/2″ knockout set. It’s designed for exposed-work applications and provides an all-in-one solution for basic switch/outlet installations. Best for quick projects or refurbishments where everything needed is packed in one purchase. Limitations include standard box size compatibility; ensure the depth matches your wall and device requirements.
Togalonn 1-Gang New Work PVC Box
TLV-listed and made of PVC, the Togalonn 1-gang box is designed for new-work installations, offering a balanced mix of durability and light-weight construction. It accommodates standard switches and GFCI receptacles, making it a flexible choice for residential and small commercial projects. Best for contractors who need a reliable, universal box that easily supports common mounting hardware. A potential drawback is that PVC boxes can require compatible clamps and fittings compatible with local codes.
Leviton Surface Mount Backbox
The Leviton surface mount backbox addresses scenarios where wall boxes are impractical or unavailable. Its breakouts are compatible with common surface raceway systems, making it ideal for projects where surface wiring is preferred or required. Best for retrofits in garages, basements, or retrofits where running a wall box is not feasible. A limitation is that it may require additional surface raceway planning and mounting hardware for a clean, code-compliant appearance.
SmarToggle Three Gang Retrofit Box
The SmarToggle retrofit box supports stud and no-stud installations, offering a flexible mounting system for remodels. With nine wiring ports and two knockouts, it adapts to complex configurations involving multiple devices. Best for multi-gang upgrades or smart-home rewiring where space and port options matter. It’s less ideal for very tight spaces due to its larger footprint compared to single-gang boxes.
Buying Guide
What installation type should you choose?
Old work boxes are best when you’re adding switches or outlets to finished walls. New work boxes are easier for new walls or new builds, offering straightforward stud mounting. Surface mount backboxes are ideal when running wiring on the surface rather than inside walls.
How much space do you need?
For most residential switches and outlets, 13–18 cubic inches is sufficient. For multiple devices or GFCIs, choose deeper or multi-gang boxes to avoid crowding and ensure proper wiring clearance.
What about fire safety and codes?
Look for ETL or UL listings and fire ratings on boxes intended for renovation or retrofit. Fire-rated boxes add protection in spaces with higher risk or where local code requires additional safety margins.
Which features help installation?
Captive screws, removable mounting tabs, and integrated nails speed installation. Boxes with rotatable buckles and snap-on connections reduce the risk of loosened devices after wiring.
Durability and material choice
PVC and plastic boxes are lightweight and resistant to corrosion, but metal may be required for certain environments or structural conditions. PVC variants are common for new-work boxes, while metal backboxes are typical in areas where metal conduit or raceways are used.
Practical considerations by buyer type
- Homeowners: Prefer boxes with clear labeling, compact depth, and easy installation for single or few devices.
- DIY remodelers: Look for new-work options with captive screws and flexible tabs to adapt to various wall depths.
- Contractors: Prioritize UL/ETL listing, compatibility with common switches/outlets, and options for multiple devices or GFCIs.
FAQ
- What is the difference between old work and new work electrical boxes?
Old work boxes are designed for retrofits in existing walls, while new work boxes are intended for new walls with stud framing. - Can one box fit multiple devices?
Yes, multi-gang boxes like the SmarToggle retrofit box are designed for several devices, but ensure enough space for wires and connectors. - Are all these boxes compliant with electrical codes?
Selected products on listing pages typically show listings (UL/ETL). Always verify local code requirements for your project. - Do PVC boxes work with metal conduits?
PVC boxes may require adapters or fittings compatible with your conduit system; check local code guidance. - When should I choose a surface mount backbox?
Choose surface mount when running wiring on or along walls without embedding into drywall, or when wall access is limited. - What box depth is best for dimmers or GFCIs?
Deeper boxes (3 inches or more) accommodate larger devices and wire bundles without crowding.
