Upgrade Your Ceiling Fan Stability with AICWIOO Cast Aluminum Hardware Stop settling for thin, rusted steel brackets that cause your fan to wobble, rattle, and squeak. The AICWIOO High-Grade Cast Aluminum Mounting Bracket is a premium, engineer-grade replacement designed for homeowners who prioritize safety and silence. Why Choose Cast Aluminum Over Stamped Steel? Anti-Corrosion Mastery: Perfect for coastal porches and patios. Unlike carbon steel, our premium aluminum never rusts, protecting your ceiling from ugly orange stains. Superior Rigidity: Our cast structure acts as a natural vibration dampener, absorbing motor harmonics to keep your bedroom or living room quiet. Seamless Fit: Designed to replace OEM brackets from major brands like Hunter and Hampton Bay, ensuring your fan remodel is smooth and professional. ?? CRITICAL COMPATIBILITY CHECK (To Avoid Returns) To ensure a successful installation and avoid the Doesnt Fit issue, please verify these 3 points before purchase: Ceiling Angle: This bracket is for flat or SHALLOW SLOPES (<10) only. For steep cathedral ceilings, please search for our Sloped Adapter (ASIN: B0FX37FMS7). Downrod Size: Precision-fitted for standard 1-inch OD downrods. It is NOT compatible with 3/4-inch systems. Hole Spacing: Fits standard 4 junction boxes with 90mm mounting centers (Adjustable range: 73mm-105mm). Whats in the Box? (Full 14-Piece Kit per Unit) We provide every fastener needed for both wood and concrete mounting. Each kit includes: 1 x Cast Aluminum Bracket: High-toughness, naturally rust-proof. 1 x Grounding Wire: Pre-attached for your safety. 2 x Expansion Screws: Specifically for concrete ceiling installations. 4 x Self-Tapping Screws: For secure mounting to wood beams or joists. 4 x Professional Wire Nuts: For clean electrical connections. 2 x Foam Gaskets: To eliminate metal-on-metal noise and vibrations. Installation Pro-Tip: For the best results and to protect the aluminum structure, please hand-tighten all screws. Do NOT use impact drivers, as high torque can cause stress fractures in cast aluminum materials.
