2. Installation (Setup)
This corner brace is designed for straightforward installation to reinforce right-angle joints. Mounting fasteners are included with the package.
Installation Steps:
- Prepare the Surface: Ensure the surfaces where the brace will be mounted are clean, dry, and free from obstructions.
- Position the Brace: Place the double-wide corner brace firmly against the interior corner joint you wish to reinforce. Ensure it sits flush against both surfaces.
- Mark Screw Holes: Using a pencil or marker, carefully mark the locations for the mounting screws through the pre-drilled holes on the brace.
- Drill Pilot Holes (Optional but Recommended): For softer materials or to prevent wood splitting, drill small pilot holes at the marked locations. Ensure the pilot holes are smaller than the screw diameter.
- Secure the Brace: Align the brace with the marked or pilot holes. Insert the provided mounting fasteners into the holes and tighten them securely with a screwdriver. Do not overtighten, as this can strip the material or damage the brace.
- Verify Stability: After installation, check the joint for improved stability and ensure the brace is firmly attached.
3. Function
The Hillman Group 851148 Double Wide Corner Brace functions as a static reinforcing angle. Once installed, it provides continuous structural support to right-angle joints, preventing movement, sagging, or separation of the joined components. It does not require any active operation after proper installation.
4. Maintenance
The zinc-plated steel construction of the Hillman Group 851148 corner brace requires minimal maintenance.
- Cleaning: Periodically wipe the brace with a clean, dry cloth to remove dust or debris. For stubborn dirt, a damp cloth with mild soap can be used, followed by thorough drying.
- Inspection: Regularly inspect the brace and its fasteners for any signs of loosening, corrosion, or damage.
- Tightening Fasteners: If fasteners appear loose, gently retighten them to ensure the brace remains securely in place.
- Corrosion: While zinc-plated for rust resistance, prolonged exposure to moisture or harsh chemicals can affect the finish. Address any signs of rust promptly by cleaning and, if necessary, applying a rust-inhibiting coating.
5. Troubleshooting
Most issues with a corner brace relate to installation or environmental factors.
| Problem | Possible Cause | Solution |
|---|---|---|
| Brace feels loose after installation. | Fasteners not fully tightened; incorrect screw size; damaged mounting surface. | Ensure fasteners are tightened securely. If screws are stripped, use slightly larger screws or repair the mounting surface. |
| Joint still wobbly or unstable. | Insufficient number of braces; brace not properly aligned; underlying structural issue. | Add more braces if necessary. Re-align the brace for optimal support. Inspect the overall structure for other weaknesses. |
| Rust or corrosion appearing on the brace. | Exposure to excessive moisture or corrosive agents; damaged zinc plating. | Clean the affected area and apply a rust-inhibiting primer and paint. Ensure the brace is used in appropriate interior conditions. |
