SECTIONAL DOORS ONLY

•Make sure garage door is fully closed. Pull the emergency release handle to disconnect the outer trolley from the inner trolley. Slide the outer trolley back (away from the door) about 2" (5 cm) as shown in Figures 1, 2 and 3.

–Fasten curved section to the door bracket in the same way, using the 5/16"x1" clevis pin.

•Figure 2:

–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 3, Hole alignment alternative:

–If holes in curved arm are above holes in straight arm, disconnect straight arm. Cut about 6" (15 cm) from the solid end. Reconnect to trolley with cut end down as shown.

–Bring arm sections together.
