Buying Guide
What to consider when choosing a low-profile gang box:
- Box depth and footprint: Match the available wall or surface space to the box’s depth to prevent project conflicts.
- Electrical vs. low-voltage needs: Use electrical boxes for outlets and switches; use low-voltage backboxes for keystone jacks and data/AV cabling.
- Mounting method: Decide between recessed or surface-mounted options based on wall structure and retrofit requirements.
- Material and fire ratings: PVC is common and durable; verify if fire ratings are required by code or wall construction.
- Knockouts and accessibility: Check the number and location of knockouts to accommodate your wiring routes and devices.
