Step 16: 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.
Type 2: Strut Mounted Bracket
Visually align the door arm connecting hole with the connecting pin
of the strut 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 with the strut mounted connecting
bracket. Insert connecting pin through the hole in the door arm.
Secure the connecting pin to the strut bracket according to the
manufacturer’s instructions.
Note: Door Bracket Mount or Strut Mount - If rod bottoms in cushion tube, cut rod to allow for proper function
of this assembly.
