Buying advice

When choosing a window screen spline, consider the material: fiberglass is more durable and weather-resistant, while vinyl is more flexible and easier to install. Match the spline diameter to your screen frame groove; common sizes are 0.125", 0.140", and 0.160". For heavy-duty or outdoor screens, opt for fiberglass; for lightweight interior screens, vinyl suffices. Also, a spline tool helps achieve a secure fit.
