INSTALLATION OF GARAGE DOOR TRIM CONTINUED:
Installing Door Header Trim:
Before you can install the door trim on the door header you will have to remove the painted screws in the lower edge
of the sheet metal panels above the door.
Install the door trim on the header first. If you have a 9’ wide door, slide the 1 1/2” upper flange of the trim under the
lower edge of the front wall sheet metal panels above the door. If the trim does not fit at the ends you may have to
clip off addition material to fit the trim at both ends. The 1 1/2” upper flange is now under the sheet metal and the
lower 3 1/2” flange is pressed against the bottom of the door header. Now, reinstall the screws in the lower edge of
the sheet metal panels over the door. If your door has two overlapping pieces of door header trim, place the right
piece in place tight to the header corner with the 1 1/2” upper flange under the front wall sheet metal panels and the
lower 3 1/2” flange pressed against the bottom of the header frame. Reinstall enough of the screws in the sheet metal
panels to hold the trim in place. Set the left side trim in place. Mark the overlap end of the trim so it overlaps the first
piece of trim at least 2” and cut the trim at your mark. Set the trim back in place and reinstall all of the screws in the
front wall sheet metal.
Installing Door Jamb Trim & Hem Trim:
Before you install the vertical Door Jamb Trim you must cut and install Hem Trim
on the cut edge of the sheet metal
panels on both sides of the door opening. Remove any painted screws that may interfere with the installation of the
edge trim. They can be reinstalled after the hem trim and the door trim are in place.
Cut two pieces of hem trim to fit from the bottom of the front wall panel up to the under side of the door header trim
that you just installed. Insert the 2 1/2” flange of the hem trim behind the panel. The 1” wide flange will sit on the out-
side of the panel. Now measure and cut a piece of door jamb trim to fit from the concrete slab to the under side of the
door jamb trim on the header. Slide the 1 1/2” flange of the trim in place and reinstall or install painted self-drilling
screws at each girt through the hem trim, the panel and the door jamb trim flange. Like the door jamb trim on the
header the 3 1/2” flange should press snugly to the vertical door frame. Repeat this assembly for the other side of the
door.
NOTE: after the garage door has been installed you will cut and install door weather seals. These will lock the 3 1/2”
flanges in place around the door opening. See page 45.
