Prime Line Products P 7940 Black Vinyl Screen Spline 25 Ft

Product Description

The PRIME LINE PRODUCTS P 7940 is a 25-foot roll of black vinyl screen spline designed to secure window and door screening material into aluminum and fiberglass screen frames. This spline measures 3/16 inches (0.185 inches) in diameter and features a round, hollow-core cross-section with a serrated outer surface. The serrated profile grips the frame channel firmly, reducing the chance of the screen working loose over time. Made from top-quality vinyl, this spline is flexible enough to seat cleanly around corners without cracking or splitting. It is a standard consumable used by screen repair technicians, glaziers, and general contractors performing window and door screen service.

This spline is suited for residential and light commercial screen replacement work. It is sized for aluminum and fiberglass screening installations where a 3/16-inch channel depth is required. The 25-foot length covers most standard single door or window screen replacements, and the package quantity of 10 rolls supports higher-volume service calls or shop inventory. The black color blends with dark-finish frames commonly found in contemporary window and door systems.

Installation Notes

Screen spline installation is typically performed by window and door service technicians or general contractors. Before replacing spline, remove the old spline and screening material completely and clean the frame channel of debris. Use a spline roller tool to press the spline and screening evenly into the channel, working from one corner and progressing around the frame to maintain consistent tension. Trim excess spline flush at the joint using a utility knife.
