To Secure the Rail on the Opener
With the End Segment of the rail fully inserted into the Rail
Bracket, insert a 5/16” x 1-1/2” Clevis Pin through the hole and
lock it into position with a Hitch Pin as shown in Fig.1.
To Assemble the Header Section of Rail
Follow steps shown in Fig.2:
1. Remove the “Trolley Shaft and Cable” from the Chain carton
and lay it beside the rail assembly. Hold Cable Eyelet on the
end of cable and thread about 20” (50cm) through the slot
on the Header Segment of the rail.
2. Temporary insert a screwdriver to the hole on the rail apart
from the slot, slide the trolley to the screw driver and keep
the position.
3. Insert the Pulley into the opening while the cable is hanging.
4. Secure the Pulley by inserting the 3/8” x 1-3/4” Clevis Pin
through the top of the rail.
5. Lock the Clevis Pin with a Hitch Pin. Rotate the Pulley to
ensure it spins smoothly.
Slide the Trolley Shaft into the Trolley until a “click” is heard
when they are connected and locked, as shown in Fig.3.
To Link Cable with Chain
Refer to Fig.4. Place the chain carton beside the rail, hold the
“Chain to Cable Connector” and pull about 8” (20cm) of chain
from the box. Thread the Chain to Cable Connector onto the
Trolley Shaft so that they are loosely linked together.

To Install Header Bracket
Note: Installation procedures may vary according to door
type.
1. While inside your garage, close the door and mark the
vertical centerline of the garage door. Extend the line onto
the header wall above the door spring.
2. Open the door to the highest point of travel. Mark a line on
the header wall 2“ (5cm) above the highest point of travel.
Note: DO NOT install the Header Bracket over drywall. In some
installations, it may be necessary to install a 2x4 across two wall
studs to create a suitable location for the Header Bracket.
If installing into masonry, use concrete anchors (not provided).
Wall-Mounting
As shown in Fig.2, place the Header Bracket on the vertical
centerline in direction shown.
Mark and drill two 3/16” holes. Fasten the Header Bracket
securely to a structural support using two 5/16” x 1-1/2” Lag
Screws.
Alternative Ceiling-Mounting
Ceiling-mounting is suggested ONLY when clearance is minimal.
Extend the vertical centerline onto the ceiling as shown in Fig.3.
Center the Header Bracket on the vertical mark, no more than
6” (15cm) from the header wall. Mark and drill holes to fasten the
Header Bracket securely to a structural support.

WARNING
To prevent SERIOUS INJURY:
- DO NOT connect power until instructed.
- The Header Bracket MUST be SECURELY fastened to the structural support on the mounting wall or
ceiling, otherwise the door may not reverse when required. DO NOT install the Header Bracket over drywall.
- Concrete anchors MUST be used when mounting the Header Bracket into masonry.
- NEVER try to loosen, move or adjust garage door springs, cables, Pulleys, Brackets, or hardware, all of
which are under EXTREME tension.
- Contact a qualified garage door service technician if your door binds, sticks or is unbalanced. An unbalanced
door might not reverse when required.

To Attach the Opener to the Header Bracket
1. As shown in Fig.1, use the packaging carton as temporary
support for the Opener. Place the Opener on carton to
prevent damage.
2. Align the mounting hole on the header rail to the mounting
hole on the Header Bracket.
3. Connect the Header Rail and the Door Bracket together
with a 5/16” x 1-1/2” Clevis Pin and lock it in place with a
Hitch Pin.
To mount the Door Bracket
Note: Some door reinforcement kits may provide direct
attachment of the door arm to the reinforcement bracket. If you
have a door reinforcement bracket with this option, skip this step
and proceed with the next step “Mounting Opener to Ceiling”.
1. Position the Door Bracket on the centerline of the door
approximately 2” - 4” (5-10cm) below the top edge of the
door, as shown in Fig.2.
2. Depending on the construction of your door, install using
one of the steps shown if Fig. 3 below:
For steel / lightweight doors with vertical steel
reinforcements / factory reinforced.
(a) Mark and drill two 3/16” holes. Make sure not to drill
through the garage door. Secure the Door Bracket with two
1/4” x 5/8” Self-Threading Screws (provided) as shown in
Fig.3(a).
(b) Alternative installation: Drill two 5/16” holes through the
door. Secure the Door Bracket using two 5/16” Bolts, lock
washers and nuts (not provided) as shown in Fig.3(b). The
length of bolts will depend on the thickness of your door.
Wood door
(c) Mark and drill two 5/16” holes through the garage door.
Secure the Door Bracket using two 5/16” carriage bolts,
washers and nuts (not provided) as shown in Fig.3(c). The
length of bolts will depend on the thickness of your door.
Note: DO NOT use Self-Threading Screws on a wood door.
