necessary to reinforce the center stile with steel

encounters an obstruction on closing.

operation, see Page 7.
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

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.

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
