Step 9: Connecting the Door Arm to the Door
Type 1: Door Mounted Bracket
Visually align the door arm connecting hole with the middle hole of
the door bracket by rotating the tube section in the appropriate
direction.
Release the trolley (leave door arm attached) with the manual release
cord and pull trolley toward the power head unit. Now rotate the door
arm tube section two turns counterclockwise (increasing the exposed
length of the door rod) to provide a cushion when the door is closed or
encounters an obstruction. Align connecting hole in the door arm to
middle hole in the door bracket; insert 3/8” diameter bolt and tighten
locking nut, allowing for free pivot of the arm. Note: Do not
overtighten locking nut as this will cause binding between the door
arm and door bracket.
