4-Gang New Work Electrical Box, Blue

The 4-Gang New Work Electrical Box from XGGYA is crafted from high-quality PVC, offering non-conductive and rust-resistant properties. Its design features nails on the side for straightforward installation, saving time during wall prep. The box provides 44 cubic inches of space, with overall dimensions around 7-1/2 inches by 3-2/3 inches by 2-3/4 inches, suitable for standard switches and outlets. It supports various conduit and wire gauges (AWG 30/14, 26/12, 24/10). This makes it a practical choice for builders prioritizing ease of use and reliability in new-construction projects.
Key considerations: Ensure your wall cavity can accommodate the 44 cu in capacity and verify compatibility with the devices you plan to install. The nail-on feature speeds up mounting but requires precise stud placement. Its PVC construction provides good resistance to weathering and corrosion, which is beneficial for various indoor applications.
Southwire MSB4G Four Gang Device Box

The Southwire MSB4G four-gang device box is built for durability with thick-wall molded PVC and reliable rigidity, making it suitable for both residential and light commercial installations. It incorporates top and bottom clamps to secure wire entry, promoting orderly cable management and easier installation. The box is designed to mount on wood or 25-gauge metal studs and adapts well to both new work and old work scenarios. This versatility makes the MSB4G a solid all-around choice when planning multiple-device configurations in a single box.
Key considerations: Evaluate whether you need top and bottom clamps for specific wiring methods and confirm that the mounting studs in your project align with the box’s mounting options. The 44 cu in capacity provides adequate space for several conductors and devices, balancing space and ease of access.
Select 8 Pack Nail On Plastic Box 4-Gang

The SELECT LIGHTING 8-pack provides 4-gang PVC boxes with a standard 44 cubic inches of space per unit. The construction is non-conductive and designed to meet quality standards for reliable performance. Dimensions approximate 7.21 x 6.58 x 2.74 inches, ensuring ample room for wire work while maintaining a tidy installation. Suitable for new projects and renovations, these boxes are a practical bulk option for electricians handling multiple rooms or outlets.
Key considerations: Bulk packs are cost-effective for large projects, but verify single-box compatibility with your device lineup. The 44 cu in capacity remains a common benchmark for 4-gang layouts, making this option easy to compare against others.
Carlon Lamson & Sessons B455A-UPC Four Gang Box

The Thomas & Betts B455A-UPC four-gang box (Lamson & Sessons) is a well-regarded option in the four-gang category, commonly used for new-work installations. While the listing emphasizes the bracket and captive nails, the box is known for stability and a reliable mounting system. This option is compatible with standard electrical devices and is designed to help installers achieve clean, finished walls with consistent performance in multiple wiring scenarios.
Key considerations: Compatibility with your electrical devices and the type of bracket or nails required for proper support are important. Consider the project’s door and frame clearances, as the box’s depth and back geometry can influence device placement and wall finishing.
Arlington 1632-N 4-Gang Low Voltage Bracket

The Arlington 1632-N is widely recognized as a 4-gang low voltage mounting bracket designed for new construction. Commonly referred to as a mud ring, this bracket helps run more wire in a structured way and supports mud-and-finish work. Its dimensions and mounting details are tailored for ease of integration with standard 2×4 wall framing and drywall, offering a practical option for installations where backbox depth is a consideration. The bracket is designed to accommodate a four-gang configuration with back access for wire routing.
Key considerations: This option is particularly suitable when you need a mud-in or open-back mounting approach. Check clearance behind the wall and confirm compatibility with the wiring devices you intend to install, as the open-back design can influence wire management and access for future upgrades.
4-Gang Plastic Electrical Box, Grey

The 4-Gang Plastic Electrical Box from Airmont Products features a spacious 55 cu in capacity, a robust PVC construction, and a slightly larger interior than typical 4-gang boxes. The dimensions are 7-3/5 inches in height, 3-7/10 inches in width, and 2-1/2 inches in depth, offering extra space for multiple switches, outlets, and complex wiring layouts. It is approved for use in fire-rated walls, making it suitable for professional installations where code compliance and long-term reliability are essential.
Key considerations: The larger interior capacity can be advantageous for dense wiring scenarios, but ensure the box fits your wall cavity and stud layout. Its fire-rated certification adds confidence for use in more demanding environments or code-specific projects.
Buying Guide: Key Purchase Considerations
- Box capacity: Most standard 4-gang boxes offer around 44 cu in; some models provide larger interiors (e.g., 55 cu in) for multi-device layouts. Choose based on the number and size of devices you plan to install.
- Material and safety: Non-conductive PVC is common for nail-on, providing rust resistance and ease of installation. Verify that the box is ETL listed and suitable for the wall type and fire-rated requirements in your project.
- Installation method: Nail-on designs simplify mounting to studs, but ensure your stud spacing aligns with the box’s mounting method. Some boxes include brackets or mud rings for open-back or adjustable depth installations.
- Compatibility: Confirm that the box accommodates the intended mix of switches, outlets, and wiring gauges (AWG 10–30 typical). Consider future expansion when selecting capacity.
- Mounting options: Some models support wood studs only, while others offer metal-stud compatibility or adjustable depth brackets. Determine whether your project benefits from adjustable depth or fixed configurations.
- Code considerations: For fire-rated walls or specific local codes, verify that the selected box is rated for those conditions. Check for compatibility with both new-work and retrofit (old-work) applications if needed.
- Value vs. bulk purchases: Bulk packs (like an 8-pack) provide cost savings for larger projects but ensure you have adequate space and device planning to avoid over-ordering.
- Finish and esthetics: For visible installations, the box color (grey, blue) can influence the final appearance. While function is primary, a match with wall finish can be desirable in some contexts.
In summary, when selecting a 4-gang nail-on box, weigh capacity, installation ease, and mounting compatibility against your project’s wall construction and device configuration. The options reviewed here cover common needs for new construction and renovations, offering a balance of reliability, ease of use, and code-ready features.
