Used with our jalousie window side strips, this aluminum header or sill frame piece finishes the installation and creates a weather tight seal and glass stop. It includes the rubber bulb seal. The picture shows the strip in the sill position.
To install as a header, simply flip it upside down. It is 1-1/8" wide and is screwed or riveted into the rough opening. Available in 25.5", 31.5" and 43.5" wide pieces and can be cut to length.
