INSTALLATION STEP 11
Connect Door Arm to Trolley
Follow only those instructions which apply to
your door type.
SECTIONAL DOORS ONLY
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.
Figure B: Bring arm sections together. Find two
pairs of holes that line up and join sections. Select
holes as far apart as possible to increase door arm
rigidity.
Figure C: If holes in curved arm are above holes in
straight arm, disconnect straight arm. Cut about
15cm from the solid end. Reconnect to trolley with
cut end down as shown.
Bring arm sections together. Find two pairs of holes
that line up and join with screws, lock washers, and
nuts.
