Before installing the transom glazing adaptor (16H8), it has to be fabricated. The cut
length is transom D.L.O. Transom D.L.O. is measured from top of door header to bottom
of transom head as shown in figure 39 on page 40.
To facilitate the installation of the door header glass stop, notch both ends of the adaptor
with a 1/2” X 7/16” notch as shown below.
Drill a .201 dia. (#7 Drill) clear hole 2” from each end and 9” on center maximum. Use the
“V” groove that is extruded into the adaptor as a guide for drill placement.
