INSTALLATION OF J-TRIM AROUND GARAGE OVERHEAD DOOR:
Cut two pieces of J-Trim to fit from the bottom of the sheeting ledge to the top of the door jamb (bottom of the door
header). This will be the side J-Trim.
Top J-Trim: If you have a 9’ wide door cut a piece of J-Trim 110” long and cut two 1” slits in both ends as shown in detail.
The slits will create tabs that will fold down into the door jamb Side J-Trim. See illustration.
If you have a 16’ wide door you will need to cut a 6’-5” long piece of J-Trim that will overlap a 10’ piece of J-Trim 3”.
Attach the Side J-Trim first at both ends and two additional places equally spaced from top to bottom with Pan Head Self-
Drilling Screws. See illustration below for location of Side J-Trim.
Place the Top J-Trim on top of the Side J-Trim along the door header. Fold the end tabs, that you created with the 1”
slits, down into the J-Trim channel and attach the at both ends and two on three places down the length with Pan Head,
Self-Drilling Screws. (Be sure to place one screw in the overlap joint if you have one.)
