The PRIME LINE PRODUCTS P 8164 is a 3-in-1 black vinyl screen spline kit used to secure window and door screens into their frames. Each package includes three spline diameters — 0.120 inches, 0.145 inches, and 0.165 inches — giving installers the flexibility to fit a wide range of standard frame groove sizes without stocking multiple separate rolls. The spline is made from vinyl, which resists weathering and retains flexibility during installation. Window and door service technicians, glaziers, and experienced DIYers use this product during screen replacement and re-screening work.
This spline kit is suited for residential screen replacement projects on windows and sliding or hinged screen doors. Having three groove-compatible diameters in one package makes it practical for service calls where the technician does not know the exact frame groove size in advance. It is also a useful stock item for shops and contractors who handle re-screening on varied window and door product lines.
Designed as a general-purpose replacement screen spline for standard residential window and door screen frames that accept 0.120-inch, 0.145-inch, or 0.165-inch groove sizes.
Screen spline installation is typically performed by window and door service technicians using a spline roller tool. Before beginning, lay the screen mesh flat over the frame and select the spline diameter that fits snugly in the frame groove without forcing or gaps. Press the spline into the groove evenly around the perimeter, keeping consistent tension on the mesh to avoid wrinkles. Trim excess spline and mesh with a utility knife after the spline is fully seated.
