Prime Line Products P 7777 Vinyl Glazing Spline 200 Ft

Product Description

The PRIME LINE PRODUCTS P 7777 is a vinyl glazing spline used to secure window screen fabric or glass panes within aluminum and wood frame channels. This spline measures 0.190 inches wide by 0.470 inches in height and comes in a 200-foot roll, giving installers enough material to complete multiple window or screen jobs from a single roll. The gray vinyl construction provides flexibility for clean, snug installation without cracking or tearing during seating. Window and door glazing technicians, general contractors, and handymen use this type of spline during new screen installation or screen re-glazing service calls.

This spline is suited for residential and light commercial window frame applications where screen fabric or glass panels require a compression fit within the frame channel. It is rated for use with single glass thicknesses from 0.085 to 0.101 inches and double glass thicknesses from 0.115 to 0.134 inches. It is sold in a package quantity of 6 rolls, making it appropriate for stocking by supply houses or contractors handling volume screen repair and glazing work.

Compatibility

Designed for use with single glass thicknesses of 0.085 to 0.101 inches and double glass thicknesses of 0.115 to 0.134 inches in standard window and door frame channels that accept a 0.190-inch wide by 0.470-inch high spline profile.

Installation Notes

Installation is typically performed by window technicians, screen repair contractors, or general maintenance trades. Before replacing spline, remove the existing spline using a flat spline roller tool or a flathead screwdriver, and ensure the frame channel is clean and free of debris. Roll the new spline into the channel using a spline roller tool, working corner to corner to maintain even tension and prevent screen fabric bunching. Do not overstretch the spline during seating, as this can cause it to pull out of the channel under load.
