Trolley Arm Configuration
Measure the horizontal radius of the horizontal track to determine if you have a 12” or 15”
radius horizontal track, as shown in FIG. 1; if you have a low headroom door skip this step.
Determine center line of the door. Mark vertical line at this point on the header, as shown in
FIG. 4. Raise the door slightly until the top section reaches the highest point of travel (high
arc), as shown in FIG. 2 and FIG. 3 for low headroom. Using a level, mark this high arc point
onto the header where it intersects the vertical center line, as shown in FIG. 4. Hold the wall
bracket’s bottom edge 1/2” - 1” (room permitting) above the high arc line and centered on
the vertical center line, as shown in FIG. 4. Mark the wall bracket’s mounting holes on the
header wall and then refer to your garage door operator manual for pre-drilling and securing
the wall bracket to header.
NOTE:
Refer to your operator manual for specific details on how to assembly the curved and
straight arm.
Align hole in the appropriate arm with holes in drawbar operator bracket tabs, as shown in
step, Trolley Arm Hookup. Insert 5/16” x 1-1/4” clevis pin, making sure hole in clevis pin is
outside of second tab of drawbar operator bracket. Insert cotter pin into clevis pin hole and
spread hairpin cotter to ensure it will secure assembly.
NOTE:
Depending on your door, configuration, you could have an alternative drawbar opera-
tor brackets. Refer to your alternative drawbar operator bracket insert.
