100 ft of Window Screen Spline: The window screen spline has an outer diameter of 0.16 in (4.1 mm) and a length of 100 ft, meeting the varying lengths needed for replacing screens on doors or windows. It can be easily cut to any desired length. Measuring tip: It is recommended to measure the gap size of the frame and select a spline that is 0.5 mm wider than the gap for optimal fit. Ideal Anti-Slip Fixing: The hollow design of the screen spline offers increased elasticity, allowing it to quickly and smoothly press into the window frame gap. The serrated shape provides more vigorous friction, ensuring the screen mesh is securely fixed and remains taut and attractive in the frame without loosening. Reliable and Durable Quality: Made from high-quality PVC material, this window screen retainer spline is flexible with good rebound elasticity, making it ideal for long-term use without aging. It is waterproof, moisture-resistant, and sunproof, capable of withstanding harsh environmental conditions, making it an ideal choice for outdoor applications. Easy Installation and Use: Even beginners can install it with ease. Cut the window spline to the appropriate length based on the window frame channel size, press it into the frame gap using a roller to secure the mesh, and trim any excess screen mesh to complete the installation. You can also use a crochet hook to remove and reuse the spline, making it convenient for replacing damaged screens. Compatible with Various Frames: This replacement spline is suitable for use with different types of metal aluminum or wooden frames as long as the size matches your needs. It is ideal for mosquito screens, balcony screen doors, patio screen doors, or pet screen doors, making it suitable for various applications.
