Prime Line Products P 7521 Screen Spline 25 Ft Black

Product Description

The PRIME LINE PRODUCTS P 7521 is a round, hollow-core vinyl screen spline designed to secure window and door screening material into aluminum and fiberglass screen frames. Measuring 0.165 inches in diameter (11/64 inches) and supplied in a 25-foot length, this spline features a serrated outer surface that grips the frame channel and holds the screen fabric firmly in place. It is manufactured from top-quality vinyl for flexibility and resistance to weathering.

This spline is suited for residential and light commercial screen frame applications. It is compatible with aluminum screen frames and fiberglass screening material, making it a versatile choice for window screens, door screens, and porch enclosure panels. The 25-foot roll provides enough material for multiple standard window or door screen replacements in a single service call. Each package contains 10 rolls.

Installation Notes

Screen spline installation is typically performed by window and door service technicians or general contractors using a spline roller tool to seat the spline evenly into the frame channel. Ensure the frame channel is clean and free of debris before beginning. Cut the spline to length with a utility knife and avoid stretching it during installation, as stretching can cause the spline to shrink back and loosen the screen over time.
