OR INSTRUCTIONS.
CAUTION!
DOOR ARM CONNECTION AND
INSTALLATION
NOTE: If the door is of light construction IT IS
necessary to reinforce the center stile with steel
angle or wood to prevent damage to the door if it
encounters an obstruction on closing.
Step 7: Connecting Door Arm to Trolley
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 rod to
the trolley ensuring the hook end goes through both
holes on the front end of the outer trolley.
Step 8: 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 and attached door
arm 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 counter-clockwise (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.
Set the outer trolley to re-engage, see page 19.
Operate the door to the full open position and return to
the fully closed position.
The position of the door
arm should be such that it’s connecting point on the
trolley is 5” to 8” behind it’s connecting point on
the door bracket. The door arm should never be
perfectly vertical when the door in in the closed
position.
