Buying Guide: Key Considerations For Back Boxes
What type of back box do I need? Choose based on installation method (surface mount vs old-work) and space constraints. Surface-mount boxes work where wall boxes aren’t feasible, while old-work boxes are ideal for renovations. Consider depth, material, and compatibility with your raceway systems or devices.
- Installation method: Surface mount vs old work (retrofit) vs specialty boxes for raceways.
- Material: Plastic PVC vs polycarbonate vs metal. Plastic boxes are common for renovations; polycarbonate offers resilience and flame resistance.
- Depth and size: Ensure the box fits the device footprint and available wall space without crowding wires.
- Carrying capacity: Look for boxes that accommodate the intended number of devices and ensure screw and cable entry compatibility.
- Finish and aesthetics: Choose colors (black, white) that blend with surrounding surfaces and trim plates.
