Step 15: Connecting Door Arm to Trolley
Activate opener to bring the trolley to the factory
The door arm assembly consists of the door arm tube section and door arm rod which are packaged separately. To assemble, screw the door arm rod into the the door arm tube in a clockwise direction approximately ten turns. Connect the door arm assembly into the trolley with the open end of the rod hook facing the power head unit (away from the door). Extend the manual release cord (connected to the trolley) and thread through the warning tag and red pull knob handle. Adjust so the knob is 6 feet above the floor and secure with a double overhand knot in the end of the release cord.

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.
