The Black .090 Screen Retainer Spline is a hollow core vinyl component used for repairing, re-screening, or fabricating window, door, and patio screens. This serrated spline features a 0.09" diameter and is supplied on a 500 ft roll. The black finish is designed to blend with charcoal aluminum or fiberglass screen wire and bronze or beige finish frames. The spline is wound on a plastic spool for handling during screen installation. This spline is a flexible material that fits into the groove of a screen frame to hold the screen mesh in place. It is used in the assembly of window screens, sliding screen doors, and patio enclosures. The serrated texture of the spline provides grip against the screen mesh and the frame channel, assisting in the retention of the material. The hollow core construction allows for compression during the installation process, which helps in seating the spline into the frame channel. This product is suitable for use in residential and commercial screen applications where a 0.09" diameter spline is required. The black color provides a neutral appearance that coordinates with various frame finishes. The 500 ft length is intended for projects requiring a significant amount of spline, such as multiple window or door screen replacements. The plastic spool keeps the spline organized and prevents tangling during use.
