Prime Line Products P 7946 Black Vinyl Screen Spline

Product Description

The PRIME LINE PRODUCTS P 7946 is a black vinyl screen spline designed to secure window and door screening material into aluminum or fiberglass screen frames. The spline features a round hollow core with a serrated exterior, which compresses and grips the frame channel to hold screening firmly in place without adhesives. Each roll provides 500 feet of continuous spline at a 0.185-inch diameter, equivalent to 3/16 inches, making it suitable for high-volume screen repair or new installation work. Window and door service technicians, glaziers, and screen installers will find this roll length practical for both residential and light commercial jobs.

This spline is intended for use with aluminum and fiberglass screening installed in standard framed screen assemblies. The 3/16-inch diameter fits screen frame channels that accept a 0.185-inch spline groove. The 500-foot roll length is well suited for contractors handling multiple screens per job or shop environments where screen fabrication is performed in volume. Each case contains 4 rolls.

Installation Notes

Screen spline installation is typically performed by window and door technicians or screen fabricators using a spline roller tool to seat the spline evenly into the frame channel. Ensure the screening material is pulled taut and aligned before rolling the spline into the groove to avoid wrinkles or gaps. Cut the spline cleanly at corners and joints to maintain a secure fit. No power tools or specialized trade licensing are required, but proper tensioning technique is critical to a long-lasting screen repair.
