Designed for new-work installation, this 1-gang box offers 18 cubic inches of capacity and adjustable mounting ears. It fits standard devices and features built-in cable clamps to secure wires. This box is well-suited for new construction or significant remodels where a sturdy, drywall-friendly box is required.
Outlet Box Kit, 2×4″ Utility Box and Cover
This kit combines a 4×2″ utility box with a 2-gang toggle switch cover and a grounding wire, making it a complete solution for projects that require both a box and a switch cover. The kit is designed for exposed work and provides a straightforward setup for outlets and switches in a single, tidy package.

Buying Guide: Key Purchase Considerations
When choosing a box for a light switch, consider the following factors to ensure you select the right solution for your project:
- Box type: Old-work boxes are ideal for retrofits, while new-work boxes suit new construction. Open-back or deep boxes may be needed for thicker walls or dense wire routing.
- Capacity and device count: Choose 1-gang, 2-gang, or 3-gang configurations based on the number of switches or outlets. Ensure there’s enough cubic inches to accommodate wires and devices without crowding.
- Material and durability: PVC (plastic) boxes resist corrosion and are easy to work with; metal boxes offer strength for certain installations. Consider climate, moisture exposure, and wall conditions.
- Mounting and compatibility: Look for adjustable mounting ears, built-in cable clamps, and compatibility with standard devices and wall thickness. Drywall thickness and stud spacing can influence the right choice.
- Environmental rating: For outdoor use, select weatherproof or rainproof enclosures with proper GFCI protection and corrosion-resistant finishes.
- Codes and safety: Ensure the box complies with local electrical codes and UL listings. Properly rated boxes reduce risks of short circuits, arcing, and heat buildup.
- Kit completeness: Some options include covers, grounding conductors, and mounting hardware. A bundled kit can simplify installation and reduce missing components during setup.
In summary, the best box for a light switch depends on whether you’re retrofitting an existing wall, wiring a new installation, or handling an outdoor setup. For remodeling, the Newhouse 1-Gang PVC Old Work Box offers flexibility and ease of use. For new construction, the Newhouse 1-Gang 18 cu in box provides substantial capacity and secure mounting.
