INSTALLATION STEP 10

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 emergency release handle to disconnect the trolley.

Manually move outer trolley back to the center of inner trolley as shown in figures A, B and C.

FIG. A: Fasten straight door arm section to outer

trolley with a clevis pin. Secure the connection with a

ring fastener.

Fasten curved section to the door bracket in the

same way.

FIG. 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.

FIG. C: 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. Find two pairs of holes

that line up and join with screws, lock washers and

nuts.
