Step 1: Prepare the Screen Frame
If replacing an existing screen, carefully remove the old screen mesh and spline from the frame. Clean the spline groove thoroughly. Ensure the screen frame is clean and free of debris.

Step 2: Position the Screen Cloth
Lay the new fiberglass screen cloth over the clean screen frame, ensuring it overlaps the frame by at least an inch on all sides. Make sure the screen is evenly aligned and relatively taut, but do not stretch it excessively at this stage.
Step 3: Install the Spline
- Begin by pressing a small section of the spline into the spline groove at one corner of the frame using the concave (grooved) end of the rolling tool.
- Work your way along one side of the frame, gently pressing the spline into the groove. Do not push it all the way in yet; just enough to hold the fabric in place.
- Repeat this process for the opposite side of the frame, then the remaining two sides. This ensures even tension.
- Once all four sides have the spline partially inserted, go back around the frame using the convex (rounded) end of the rolling tool. Apply firm, even pressure to fully seat the spline into the groove, securing the screen cloth.

Step 4: Trim Excess Screen and Spline
Once the spline is fully seated and the screen is taut, use a utility knife or a sharp blade to carefully trim away the excess screen cloth that extends beyond the spline. Cut along the outer edge of the spline for a clean finish. Trim any excess spline from the corners.

Maintenance
To ensure the longevity of your newly installed screen, regular maintenance is recommended:
- Cleaning: Periodically clean the screen with mild soap and water using a soft brush or cloth. Rinse thoroughly with clean water.
- Inspection: Regularly inspect the screen for any signs of damage, tears, or loose spline. Address minor issues promptly to prevent further damage.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals on the screen, as this can degrade the fiberglass material.
Troubleshooting
If you encounter issues during or after installation, consider the following:
- Screen Sagging: If the screen appears loose or sags, it may not have been pulled taut enough during installation, or the spline may not be fully seated. Re-roll the spline with firm pressure, ensuring the screen is stretched evenly.
- Spline Not Seating: Ensure the spline is the correct diameter for your frame's groove. If slightly too thick, gently stretching the spline may help it to fit. The rolling tool should be used with consistent pressure.
- Tears During Installation: Apply even pressure with the rolling tool and avoid sharp objects near the screen. If a tear occurs, you may need to replace the screen cloth.
