ALL ONE-PIECE DOORS

1. Assemble the door arm, Figure 4:

 • 

 

Fasten the straight and curved door arm sections 
together to the longest possible length (with a 2 
or 3 hole overlap).

 • 

 

With the door closed, connect the straight door 
arm section to the door bracket with the
5/16"x1-1/4" clevis pin.

 • 

 

Secure with a ring fastener.

2. Adjustment procedures, Figure 5:

 • 

 

On one-piece doors, before connecting the door 
arm to the trolley, the travel limits must be 
adjusted. Limit adjust ment screws are located on 
the left side panel as shown on page 23. Follow 
adjustment procedures below.

 • 

 

Open door adjustment: decrease UP 
travel limit

    -  Turn the UP limit adjustment screw 

counter-clockwise 4 turns.

    -  Press the Door Control push button. The trolley 

will travel to the fully open position.

    -  Manually raise the door to the open position 

(parallel to the floor), and lift the door arm to the 
trolley. The arm should touch the trolley just in 
back of the door arm connector hole. Refer to 
the fully open trolley/door arm positions in the 
illustration. If the arm does not extend far 
enough, adjust the limit further. One full turn 
equals 2" (5 cm) of trolley travel.

 • 

 

Closed door adjustment: decrease DOWN 
travel limit

    -  Turn the DOWN limit adjustment screw 

clockwise 4 complete turns.

    -  Press the Door Control push button. The trolley 

will travel to the fully closed position.

    -  Manually close the door and lift the door arm to 

the trolley. The arm should touch the trolley just 
ahead of the door arm connector hole. Refer to 
the fully closed trolley/door arm positions in the 
illustration. If the arm is behind the connector 
hole, adjust the limit further. One full turn equals 
2" (5 cm) of trolley travel.

3. Connect the door arm to the trolley:

 • 

 

Close the door and join the curved arm to the 
connector hole in the trolley with the remaining 
clevis pin. It may be necessary to lift the door 
slightly to make the connection.

 • 

 

Secure with a ring fastener.

 • 

 

Run the opener through a complete travel cycle. If 
the door has a slight "backward" slant in full open 
position as shown in the illustration, decrease the 
UP limit until the door is parallel to the floor.

NOTE:

 

When setting the up limit on the following 

page, the door should not have a "backward" slant 
when fully open as illustrated below. A slight 
backward slant will cause unnecessary bucking and/
or jerking operation as the door is being opened or 
closed from the fully open position.
