Prime Line Products P 7645 Screen Spline 0.250 in Gray 25 Ft

Product Description

The PRIME LINE PRODUCTS P 7645 is a gray vinyl screen spline designed to secure window and door screening material into aluminum and fiberglass screen frames. Measuring 0.250 inches in diameter and 25 feet in length, this round, hollow-core spline features a serrated exterior profile that grips the frame channel securely once seated. Made from top-quality vinyl, it resists cracking and deformation under normal service conditions. Each package contains 10 individual rolls, making it well suited for screen repair contractors, window and door service techs, and facilities maintenance crews handling multiple screens in a single job.

This spline is used in residential and light commercial window screen, door screen, and porch screen replacement or new installation work. It is appropriate for use wherever a 0.250-inch spline channel is specified in aluminum or fiberglass screen frame systems. The serrated surface helps lock the screen material in place without requiring adhesives, reducing installation time on high-volume screen jobs.

Compatibility

Designed for use with aluminum and fiberglass screening material in screen frames that accept a 0.250-inch round spline groove.

Installation Notes

Screen spline installation is typically performed by window and door service technicians or general contractors using a spline roller tool to press the spline into the frame channel over the screen material. Verify the frame channel width matches the 0.250-inch spline diameter before installation — using an oversized spline can split the frame corner joints. Trim excess spline flush at the corner after fully seating the run. No power tools or special codes are required, but work on elevated or large fixed frames should follow applicable fall-protection practices.
