FRONT DOOR WINDOW ASSEMBLY-
"A-17and 67" Styles
The front door window is a solid tempered safety
glass that fits into a lower sash channel which in-
corporates a welded-on cam. With this design, the
door glass, lower sash channel and sash channel
cam are removed from the door as a unit.
CAUTION:
Use care to make certain glass does
not strike hard objects. Edge chips or deep
scratches can cause solid tempered safety glass
to shatter. Do not attempt to grind or drill glass.
