This Aluminum Extrusion was developed with three uses in mind:
(1) As a U-Channel that would be the same width as our Sidelite Rails and Door Rails;
(2) As a Narrow Header that is the same width as our Sidelite Rails and Door Rails, and will accept a Top Free-Swinging Pivot to secure the top of the doors;
(3) As an Even Sight Line System, accomplished by first securing the fabricated Narrow Header to the top of the opening, then securing the Sidelite Rail to the Narrow Header with the 1/4" (6 mm) Header Saddle. All drilling, tapping, and fabrication can be done at your request during manufacturing to save time while installing.
