The Black 0.150 Screen Retainer Spline is a hollow core vinyl component used for repairing, re-screening, or fabricating window, door, and patio screens. This spline features a 0.15" diameter and a serrated design, which assists in securing screen mesh within the frame. It is supplied on a 500 ft roll, providing sufficient material for multiple screening projects. The black finish is intended to blend with charcoal aluminum or fiberglass screen wire and bronze or beige finish frames. This vinyl material is designed for use in standard window and door screening applications. The hollow core construction allows for flexibility during the installation process, making it easier to press the spline into the screen frame channel. This spline is compatible with various screen frame materials and is a standard choice for maintaining window and door screens. The 500 ft length ensures that there is enough material for large-scale projects or multiple smaller repairs. The serrated surface provides a grip against the screen mesh, helping to keep the material taut within the frame channel. This product is a functional accessory for window and door screening supplies.
