INSTALLATION STEP 12

Connect Door Arm to Trolley

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

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 8" (20 cm) as shown in Figures 1, 2 and 3.

• Figure

1:

- 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.

IMPORTANT:

The groove on the straight door arm MUST

face away from the curved door arm (Figure 4).

• 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.

- 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.
Proceed to Adjustment Step 1, page 28. Trolley will
re-engage automatically when opener is operated.
