Setup and Installation
This door frame kit is designed for ease of assembly and can be painted to match your door. Follow these steps for proper installation:
- Prepare the Door: Ensure your door has a cut opening of exactly 21 inches x 65 inches. The door itself should be 1 3/4 inches thick.
- Glass Thickness Note: This frame is specifically designed for 1/2 inch thick glass. Using glass of a different thickness may result in an improper fit.

- Insert Glass: Carefully place your 20 inch x 64 inch, 1/2 inch thick glass panel into the door opening.
- Position Frame Halves: Place one half of the frame on the interior side of the door and the other half on the exterior side, aligning them around the glass and the door opening.
- Secure with Screws: Insert the provided screws through the designated holes in the frame. Tighten them evenly to secure both frame halves together, sandwiching the glass and the door. Do not overtighten.
- Install Plugs: Once the frame is securely fastened, insert the screw plugs into the screw holes for a finished appearance.

Maintenance
The RSL Universal Door Frame Kit is designed for low maintenance. The material is resistant to yellowing and warping. To maintain its appearance:
- Cleaning: Clean the frame with a soft cloth and mild soap and water. Avoid abrasive cleaners or solvents that could damage the finish.
- Inspection: Periodically check the screws for tightness and ensure the plugs are securely in place.
- Painting: If desired, the frame is easy to paint. Ensure the surface is clean and dry before applying paint suitable for plastic surfaces.
Troubleshooting
- Frame Does Not Fit: Double-check your door's cut-out dimensions and thickness against the specifications. Ensure the glass thickness is exactly 1/2 inch.
