The MD spline is the component used to hold screen in screen frame. Our 0.16 In. x 25 ft spline is recommended to use with fiberglass, extra strength, and small bug screens (may vary based on frame size). Pairing the correct spline, screen and frame will ensure your screens go in easily and remain in place for years to come.
