Buying Guide
- Work Type: Choose Old Work boxes for retrofits into existing walls and New Work boxes for fresh-wall installations. The box’s depth and mounting features should align with your wall cavity and stud layout.
- Capacity: 14 cu in models are compact and suited for simple single-switch or single-outlet installs, while 18 cu in boxes provide extra space for more wires or devices. Plan for wire count and device size when selecting.
- Material and Certification: PVC boxes are non-conductive and corrosion-resistant. Look for ETL or UL listings to ensure electrical safety and code compliance for your area.
- Installation Features: Caps or nails captive for fast mounting, removable or adjustable tabs, and rotatable buckles can simplify alignment and reduce installation time in tight spaces.
- Color and Visibility: Blue boxes are easy to locate and can help differentiate circuits in multi-box installs, but ensure compatibility with your existing hardware and local building codes.
- Pack Size: If you’re wiring multiple outlets or switches, consider bundles (like packs of 3 or 10) to ensure consistency across installations and reduce missing pieces.
- Durability and Depth: Deeper boxes accommodate larger conductors and more complex wiring. Check depth measurements to avoid wall-space conflicts and ensure a flush finish with faceplates.
