Buying Guide
What should you consider when choosing a single gang retrofit box?

- Depth and capacity: Ensure 14 cu in or more for comfortable wiring and avoid crowding conductors.
- Material: PVC boxes are lightweight and non-conductive; fire-rated designs add protection for certain installations.
- Device compatibility: Decide whether the box will house a switch, GFCI, or duplex receptacle, and verify knockout and wiring-port counts.
- Installation method: Old-work boxes should offer easy retrofit installation with mounting ears or locking tabs; avoid boxes requiring extensive wall damage.
