Pro tips for best results
- Measure groove width accurately and cut the spline slightly longer than the required length to ensure a snug fit.
- Clean the groove before seating the spline to prevent debris from causing an uneven lay.
- Use a spline roller to press the spline evenly into the groove, working in short, steady passes to avoid gaps.
- Install across corners to reduce fabric slack and help the screen sit evenly.
