Prime Line Prime-line P 7520 Screen Retainer Spline, Black Vinyl, 5/32 In., 25 Ft.

Prime-Line's black vinyl screen retainer spline is designed to secure screen fabric into window screen and screen door frames. This 25-foot roll of premium-grade spline works with both aluminum and fiberglass frames, providing a tight, professional seal that keeps insects out and screens in place. The hollow-core construction keeps the material lightweight and flexible, while the serrated profile slides smoothly into the frame groove for quick, reliable installation.

Whether you're repairing a single window screen, replacing a damaged patio screen door, or building a new screening project from scratch, this spline delivers durable, long-lasting performance. The deep-black vinyl resists UV fading, cracking, and moisture absorption, so your screens stay secure season after season without frequent replacement or maintenance.
