Prime Line Products P 7573 Black Vinyl Screen Spline

Product Description

The PRIME LINE PRODUCTS P 7573 is a black vinyl screen spline designed for securing window and door screen mesh into aluminum and fiberglass frame channels. This round, hollow-core spline features a serrated exterior profile that grips the frame channel and holds screening material firmly in place. It measures 0.165 inches (11/64 inches) in diameter and comes in a 1,500-foot roll weighing 15 pounds. Fabricated from top-quality vinyl, it resists cracking and maintains flexibility during installation, reducing breakage when working the spline into tight or angled channels.

This spline is suited for residential and light commercial screen replacement and repair work on windows and doors. Installers use it when re-screening aluminum-framed or fiberglass-framed window and door units. The 1,500-foot roll is packaged as a single roll, making it practical for high-volume screen shops, glazing contractors, and service techs handling multiple units per job.

Key Features

• 0.165 inch (11/64 inch) diameter fits standard aluminum and fiberglass frame spline grooves
• Round hollow-core construction reduces splitting and allows consistent compression into the channel
• Serrated outer surface grips frame channel walls to keep screen material locked in position
• Top-quality vinyl formulation maintains flexibility and resists brittleness over time
• 1,500-foot roll length reduces mid-job splicing on large or high-volume projects
• Black color for a clean, finished appearance on dark-framed screen assemblies

Compatibility

Designed as a replacement screen spline for use with aluminum and fiberglass window and door screen frames that accept a 0.165 inch diameter round spline channel.

Installation Notes

Screen spline installation is typically performed by glaziers, window service technicians, or experienced handymen using a spline roller tool. Lay the replacement screen mesh over the frame before pressing the spline into the channel groove; avoid stretching the mesh unevenly, as this causes bowing. Cut spline ends cleanly with a utility knife at corners rather than attempting to bend continuous spline around sharp angles. No power tools or fasteners are required, but work in moderate temperatures when possible, as extreme cold can reduce vinyl flexibility during installation.
