Follow instructions which apply to your door type
as illustrated below and on page 23.

inner trolley. Slide the outer trolley back (away from the door) about 2" as shown in Figures 1, 2 and 3.

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.

• If holes in curved arm are
above holes in straight arm,
disconnect straight arm. Cut about 6" from the solid
end. Reconnect to trolley with cut end down as shown.
• Bring arm sections together.

screws, lock washers and nuts.
