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.

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.
