Prime Line Products P 7774 Vinyl Glazing Spline 200 Ft

Product Description

The PRIME LINE PRODUCTS P 7774 is a vinyl glazing spline used to secure glass panes within window and door screen frames. Measuring 0.160 inches wide by 0.390 inches in height and supplied in a 200-foot roll, this spline fits a range of glass thicknesses from 0.085 to 0.101 inches for single glass and 0.115 to 0.134 inches for double glass. Glaziers, window repair technicians, and screen installers use this spline when replacing or re-glazing residential and light commercial window frames. The gray vinyl construction resists moisture and maintains flexibility across typical service temperatures.

This spline is suited for residential and light commercial window and door screen applications where glass must be retained securely within a channel frame. It is appropriate for new installations and replacement service work on both single-pane and double-pane glass assemblies. Each roll provides 200 feet of continuous spline, making it practical for multi-unit jobs or high-volume screen repair work. Sold in packages of 6 rolls per package quantity.

Compatibility

Designed as an OEM-style replacement spline for window and door screen frames accepting a 0.160-inch wide by 0.390-inch spline profile, with glass thickness compatibility of 0.085 to 0.101 inches single glass and 0.115 to 0.134 inches double glass.

Installation Notes

Installation is typically performed by glaziers or window and door service technicians using a spline roller tool to seat the spline evenly within the frame channel. Remove the existing spline and clean the channel before installing new material. Avoid stretching the spline during installation, as elongation can result in poor retention and premature pullout. Confirm glass thickness falls within the rated range before selecting this spline profile.
