WALL MOUNTING BRACKET AND OPERATOR INSTALLATION:
NOTE: Trolley type operators should generally be mounted directly over the center of the door and the trolley rails should
clear the tracks by 2-1/2” (6.5 cm). However, if interfering structures or other reasons do not allow for centered mounting, it
is possible to install it up to 18” off-center for torsion spring doors.
1. With door closed, locate the center of door by measuring door width and mark a vertical line above the door (Fig A).
2. Open door and mark the center line of the door on the ceiling (Fig B).
3. Determine the highest point of door travel by manually opening the door. Using a carpenter’s level, project a line from
where the top section of door reaches its highest point. Mark the spot where this line (high arc) intersects with the
vertical line drawn earlier.
4. Close door. Lay out operator/rail assembly on ground (upside down) in front of door with door operator facing away
from door.
5. Install curved trolley arm/door bracket to the trolley arm flat bar that is connected to the carriage. (Fig C). The trolley
arm is adjustable so do not tighten bolts at this time.
