INSTALLATION STEP 9
CONNECT DOOR ARM TO TROLLEY
Follow instructions which apply to your door type as illustrated below
and on the following page.
IMPORTANT: The groove on the straight door arm MUST face away
from the curved door arm (Figure 4).
SECTIONAL DOORS ONLY
1. 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 pulley)
about 8" (20 cm) as shown in Figures 1, 2 and 3.
2. Fasten straight door arm section to outer trolley with the
5/16"x1" clevis pin. Secure the connection with a ring fastener
(Figure 1).
3. Fasten curved section to the door bracket in the same way,
using the 5/16"x1-1/4" clevis pin.
4. 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 2).
Hole alignment alternative (Figure 3):
• 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.
• Find two pairs of holes that line up and join with bolts, lock
washers and nuts.
Pull the emergency release handle toward the opener at a 45° angle
so that the trolley release arm is horizontal. Trolley will re-engage
automatically when opener is operated during the adjustments.
