Newhouse Hardware 1-Gang PVC Old Work Box

It uses plastic construction compatible with non-metallic sheathed cable and provides a 14 cubic inch interior to accommodate switches, GFCI, or a duplex receptacle. Its old-work design enables installation without extensive wall framing, making it suitable for retrofit applications in homes or light commercial spaces. The box is designed to withstand typical remodeling activities while maintaining electrical safety and code compliance in non-metal environments.
Key considerations for this box include compatibility with common outlets, ease of retrofit, and the durability of PVC material in interior walls. For renovations where non-metallic wiring is standard, this box provides a straightforward mounting option with reliable support for everyday devices. Users should verify wall clearance and the specific box depth to ensure proper fit behind existing drywall or plaster.
Legrand OnQ In-Wall Media Box
The On-Q In-Wall Media Box is designed specifically for structured wiring and AV components. Its in-wall storage focus helps keep a clutter-free setup behind your TV, providing space for devices like streaming boxes and network gear. Its compatibility with various TV mounts, including premium mounts from brands such as SANUS, offers flexible placement behind the screen. The enclosure accommodates devices and cables while maintaining a clean living area and reducing visible wires behind the wall.
Considerations for this box include its emphasis on in-wall organization and AV device compatibility. It is a practical choice for homeowners looking to hide media components while maintaining access to connections. When installing, ensure you have the required depth behind stud spaces to house equipment and cable management accessories without overfilling the enclosure.
XGGYA Old Work Box, Plastic Junction
The XGGYA Old Work Box focuses on ease of use for adding new outlets to existing walls. It includes built-in fixing ears and a rotatable buckle to secure the box, reducing the risk of it falling during installation. The product highlights quick, tool-efficient installation with snap-on connections to prevent loosening. The box dimensions—approximately 4-1/3 inches long, 2-1/5 inches wide, and 2-3/4 inches deep—balance compactness with adequate space for standard wiring and devices.
When choosing this box, consider its installation method and the wall type. The design supports a straightforward retrofit in many interior walls, though it’s important to confirm fit with your specific drywall thickness and stud configuration. The AWG compatibility and snap-on connections contribute to a reliable, durable fixture for everyday electrical upgrades.
Perlegear 17″ In-Wall Media Box
The Perlegear 17″ in-wall media box is designed to host multiple devices and a cable management system. It provides ample internal space for media boxes, network switches, and streaming devices. The kit includes a cutting template, dust bag, and drywall saw to facilitate a clean, integrated installation for a clutter-free entertainment wall. Fire-resistant materials are noted in its construction, adding a layer of safety for in-wall installations, especially behind TVs or media centers.
Considerations for this model include ventilation, heat dissipation for active devices, and compatibility with your wall thickness and stud layout. The larger footprint supports more devices and reduces congestion behind a wall-mounted television. For homeowners seeking a comprehensive behind-the-screen solution, this box offers organized, concealed storage with modularity for future additions.
CLOUDY BAY Round Electrical Box Set
This 3-pack of round old-work boxes offers a compact solution for round junction needs. UL Listed, these pancake-style boxes are suitable for ceilings or walls with standard mounting screws spacing. Built from polycarbonate, they resist rust and do not conduct electricity, contributing to safety in various environments. The round design provides flexibility for recessed lighting, ceiling fixtures, or other in-wall installations where circular boxes are preferred.
Key considerations include the suitability of round boxes for your specific outlets and the spacing of screws or knockouts. These boxes can be a practical option when round form factors align with the planned wiring layout. Always verify compatibility with your outlet type and drywall thickness to ensure a proper, secure fit.
Buying Guide
When selecting an in-wall junction box, consider the following factors to ensure a safe, compliant, and durable installation:
- Box type and use case: Old-work (remodel) boxes suit retrofit projects, while in-wall media or enclosure boxes are better for organized AV and networking systems.
- Material: PVC/plastic boxes resist corrosion in interior spaces but may have different rigidity than metal boxes. Choose based on wall type and local building codes.
- Interior capacity: Ensure cubic inch capacity aligns with the devices you plan to install, including switches, receptacles, and low-voltage components.
- Depth and framing: Confirm wall cavity depth and stud spacing to accommodate box dimensions without crowding wires.
- Environmental considerations: Fire resistance, moisture tolerance, and UL or ETL listings affect safety and longevity in different rooms (kitchens, bathrooms, outdoors).
- Compatibility: Check device compatibility, including GFCI, USB outlets, or media devices, to avoid space constraints.
- Installation complexity: Some boxes include fixing ears, rotatable buckles, or cut templates—evaluate what will speed up the job and reduce errors.
- Cable management: For AV installations, prioritize solutions with integrated routing, dust protection, and easy cable exits behind TVs or wall panels.
Overall, the right in-wall junction box balances installation ease, space for devices, and long-term safety. Evaluate remodeling plans, the planned devices, and wall construction to choose a box that minimizes future maintenance while keeping wiring compliant with electrical codes.
