ASSEMBLY STEP 1
ASSEMBLE THE RAIL AND INSTALL THE
TROLLEY
To prevent INJURY from pinching, keep hands and fingers away
from the joints while assembling the rail.
To avoid installation difficulties, do not run the garage door opener
until instructed to do so.
The front rail has a cut out “window” at the door end. The front rail has
a rail tab. This tab MUST be on the top of the rail when assembled.
1. Remove the straight door arm and hanging bracket packaged
inside the front rail and set aside for Installation Step 5 and 9.
NOTE: To prevent INJURY while unpacking the rail carefully
remove the straight door arm stored within the rail section.
2. Align the rail sections on a flat surface as shown and slide the
tapered ends into the larger ones. Tabs along the side will
lock into place.
3. Place the motor unit on packing material to protect the cover,
and rest the back end of the rail on top. For convenience, put
a support under the front end of the rail.
4. As a temporary stop, insert a screwdriver into the hole 10" (25
cm) from the front end of the rail, as shown.
5. Check to be sure there are 4 plastic wear pads inside the
inner trolley. If they became loose during shipping, check all
packing material. Snap them back into position as shown.
6. Slide the trolley assembly along the rail from the back end to
the screwdriver.
7. Slide the rail onto the “U” bracket, until it reaches all the stops
on the top and sides of the “U” bracket.

ASSEMBLY STEP 2
FASTEN THE RAIL TO THE MOTOR UNIT
To avoid SERIOUS damage to garage door opener, use ONLY
those bolts/fasteners mounted in the top of the opener.
1. Insert a 1/4"-20 x 1-3/4" bolt into the cover protection bolt hole
on the back end of the rail as shown. Tighten securely with a
1/4"-20 lock nut. DO NOT overtighten.
2. Remove the bolts from the top of the motor unit.
3. Use the carton to support the front end of the rail.
4. Place the “U” bracket, flat side down onto the motor unit and
align the bracket holes with the bolt holes.
5. Fasten the “U” bracket with the previously removed bolts; DO
NOT use any power tools. The use of power tools may
permanently damage the garage door opener.
