Prime-Line P 7843 Flat Screen Spline

This flat screen spline is constructed of UV-stabilised extruded vinyl in a black finish. It measures 5/16 in. (.315) wide by .092 in. tall and is supplied as a 100 ft. roll. The profile features a flat bottom and a curved top edge designed for aluminium screen frames.

Replaces worn or damaged spline in existing screens

The spline is used for installing fiberglass screen mesh into aluminium screen frames by laying it flat into the spline channel over the mesh. The inner edge inserts under the frame lip before the outer edge is rolled in. A Prime-Line P 8228 flat spline rolling tool is recommended for the installation process.

100 ft. roll suits multiple window and door screens

The length provides ample material for several standard screen repairs or a full rescreening project. Vinyl construction resists UV degradation for extended outdoor service. The fixed 5/16 in. width limits use to frames with a matching channel; narrower or wider channels require a different spline size.
