When it comes to installing a ceiling fan, most homeowners focus on blade size, airflow, or light kits. But one of the most critical components is often overlooked—the ceiling fan mounting box. Without a secure, code-compliant mount, even the best fan can become a hazard.
That’s where the RACO Kwik-Brace Round Steel Gang Fan Box shines. Built for durability, strength, and ease of installation, it ensures your ceiling fan is safely mounted and solidly supported.
Why a Proper Ceiling Fan Mounting Box Matters
Standard electrical boxes aren’t always rated to support the weight and motion of a ceiling fan. Using one can lead to wobbling, noise, or even a falling fan—posing a serious safety risk.
A fan-rated mounting box, like the RACO Kwik-Brace, is specially designed to handle:
- The fan’s weight
- Continuous motion/vibration
- Long-term ceiling support
Features of the RACO Kwik-Brace Ceiling Fan Mounting Box
✅ 1. Heavy-Duty Steel Construction
Made from steel, the RACO gang box provides superior strength compared to plastic alternatives. It won’t flex, crack, or degrade over time.
✅ 2. Kwik-Brace Adjustable Support
The built-in Kwik-Brace expands to fit joist spaces between 16″ to 24″, making it ideal for both new construction and retrofit projects.
✅ 3. Fan- and Fixture-Rated
UL-listed for ceiling fans up to 70 lbs and light fixtures up to 90 lbs—meeting national electrical code standards.
✅ 4. Easy, Tool-Free Installation
No need for complex mounting systems. The brace twists into place between ceiling joists, and the box attaches securely with just a few steps.
✅ 5. Secure Cable Entry
Includes multiple knockouts and clamps to safely route electrical wires and reduce wear on insulation.
