IMPORTANT:
Warning tags must be securely attached to end bracket(s).
IMPORTANT:
For single spring doors, ensure the left hand cable drum bearing is all the
way to the left and up against the flag angle. If the cable drum is pulled away from the flag
angle, then the idler bracket can rub against the cable drum causing noise.
NOTE:
Drill 3/16” pilot holes into header for the lag screws.
