Buying Guide
- Box depth and size: Choose depth that accommodates your fan housing and ceiling clearance. Deeper boxes support heavier fixtures but require more space.
- Joist spacing: Adjustable braces help when joist centers vary. For renovations, retro-fit braces are often the easiest choice.
- Weight rating: Verify the fixture’s weight and select a box or brace rated to exceed it by a safe margin.
- New construction vs remodel: Some braces are designed for old-work installations, while others are optimized for new builds.
- Code and compatibility: Ensure the box is rated for ceiling fans if you plan to install a heavy fan, not just a light fixture.
- Ease of installation: Look for features like built-in mounting rings, knockouts, and tool-free adjustments to speed setup.
