Installation Guide
Installing the Prime-Line P 7571 spline is a straightforward process, typically requiring a spline roller tool (not included). Follow these steps for effective screen installation:
- Prepare the Frame: Ensure the window or screen door frame is clean and free of old spline or debris. Lay the frame flat on a stable surface.
- Position the Screen Fabric: Place the new screen fabric over the frame, ensuring it overlaps the spline channel by at least an inch on all sides. Keep the fabric taut but do not stretch it excessively yet.
- Initial Spline Insertion: Starting at one corner, gently press a small section of the spline into the channel using the concave wheel of a spline roller tool. Do not cut the spline yet.
- Secure One Side: Work your way down one side of the frame, pressing the spline into the channel. As you go, apply gentle tension to the screen fabric to keep it straight and flat.
- Secure Adjacent Sides: Move to an adjacent side. As you insert the spline, pull the screen fabric taut across the frame. This is crucial for a wrinkle-free screen. Continue around the remaining sides, maintaining even tension.
- Trim Excess: Once the spline is fully inserted around the entire perimeter, use a utility knife or sharp scissors to carefully trim the excess screen fabric flush with the outer edge of the spline channel. Trim the spline itself where the ends meet.
- Final Check: Inspect the screen for any loose areas or wrinkles. If necessary, carefully remove a section of spline, re-tension the screen, and re-insert the spline.

Operation and Usage
Once properly installed, the Prime-Line P 7571 spline securely holds your screen fabric in place, allowing your window or door screen to function as intended. The screen provides ventilation while keeping insects and debris out. No specific operational steps are required for the spline itself after installation.
Maintenance
To ensure the longevity of your screen and the spline, consider the following maintenance tips:
- Regular Cleaning: Periodically clean your screen with mild soap and water to remove dirt and grime. Avoid harsh chemicals that could degrade the spline material.
- Inspect for Damage: Annually inspect the spline for any signs of cracking, shrinking, or loosening, especially in areas exposed to direct sunlight.
- Avoid Punctures: Protect the screen from sharp objects or excessive force that could dislodge the spline or damage the screen fabric.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Spline keeps popping out of channel. | Incorrect spline size, insufficient pressure during installation, or channel is dirty/damaged. | Ensure you are using the correct spline diameter (0.165 inch). Re-insert spline with firm, even pressure using a spline roller. Clean the channel thoroughly. |
| Screen fabric is wrinkled or loose. | Uneven tension applied during installation. | Carefully remove the spline from the affected area, re-tension the screen fabric evenly, and re-insert the spline. Work slowly around corners. |
| Spline is difficult to insert. | Spline is too large for the channel, or channel is obstructed. | Verify the channel size. Ensure the channel is clear of debris. If the spline is too large, you may need a different size. |
