headroom is insufficient.

garage door. Place a 2x4 on the top section of door near
centerline as shown. Rest T-rail on 2x4 as shown.
INSTALLATION - 1-PIECE DOOR WITHOUT TRACK
PROCEDURE: Measure the distance from floor to top of
door (in fully open position and parallel to the floor). Using
a stepladder as a support, raise opener to the same
distance from the floor (it will have a slight angle as
shown).
The top of the door should be level with the top of
opener. For maximum efficiency, do not position opener
more than 2 inches above this point.
