Follow only those instructions which apply to
your door type.
Make sure garage door is closed tight. Pull the manual release handle to disconnect the outer trolley from the
inner trolley. Slide the outer trolley back (away from the door) about 2" as shown in figures A, B and C.
Figure A: Fasten straight door arm section to outer
trolley with the 5/16"x1" clevis pin. Secure the
connection with a ring fastener. Fasten curved
section to the door bracket in the same way, using
the 5/16"x1-1/4" clevis pin.
