STEP 16:
Connect one end of the straight door arm to the trolley. Attach to the trolley using the
short clevis pin and its clip.
Usually the straight arm is all that is required on tilting doors. Usually the L arm is attached between
the door and the straight arm for use with sectional doors. You may have to shorten or re-drill the
door arm.
You may need to use the L-arm to prevent fouling of the door in
the fully open position.
CAUTION When the door is fully closed the door arm
must not ever become vertical. The door arm must
remain at less than a right angle to the pole.
Disengage the trolley.
Connect the free end of door arm assembly to the door
bracket.
