INSTALLATION STEP 1

Determine the Header Bracket
Location

Installation procedures vary according to garage door
types. Follow the instructions which apply to your door.

1. Close the door and mark the inside vertical centerline of

the garage door.

2. Extend the line onto the header wall above the door.

You can fasten the header bracket within 4' (1.22 m)
of the left or right of the door center only if a torsion
spring or center bearing plate is in the way; or you
can attach it to the ceiling (see page 9) when
clearance is minimal. (It may be mounted on the wall
upside down if necessary, to gain approximately
1/2" (1 cm).)

If you need to install the header bracket on a 2x4
(on wall or ceiling), use lag screws (not provided)
to securely fasten the 2x4 to structural supports as
shown here and on page 9.

3. Open your door to the highest point of travel as shown.

Draw an intersecting horizontal line on the header wall
above the high point:

• 2" (5 cm) above the high point for sectional door and
one-piece door with track.

• 8" (20 cm) above the high point for one-piece door
without track.

This height will provide travel clearance for the top edge
of the door.

NOTE: If the total number of inches exceeds the height
available in your garage, use the maximum height
possible, or refer to page 9 for ceiling installation.

To prevent possible SERIOUS INJURY or DEATH:

• Header bracket MUST be RIGIDLY fastened to structural
support on header wall or ceiling, otherwise garage door
might not reverse when required. DO NOT install header
bracket over drywall.

• Concrete anchors MUST be used if mounting header bracket
or 2x4 into masonry.

• NEVER try to loosen, move or adjust garage door, springs,
cables, pulleys, brackets, or their hardware, ALL of which
are under EXTREME tension.

• ALWAYS call a trained door systems technician if garage
door binds, sticks, or is out of balance. An unbalanced
garage door might not reverse when required.

WALL HEADER BRACKET INSTALLATION

• Center the bracket on the vertical centerline with the
bottom edge of the bracket on the horizontal line as
shown (with the arrow pointing toward the ceiling).

• Mark the vertical set of bracket holes (do not use the
holes designated for ceiling mount). Drill 3/16" pilot
holes and fasten the bracket securely to a structural
support with the hardware provided.

CEILING HEADER BRACKET INSTALLATION

• Extend the vertical centerline onto the ceiling as shown.

• Center the bracket on the vertical mark, no more than
6" (15 cm) from the wall. Make sure the arrow is
pointing toward the wall. The bracket can be mounted
flush against the ceiling when clearance is minimal.

• Mark the side holes. Drill 3/16" pilot holes and fasten
bracket securely to a structural support with the
hardware provided.

ONE-PIECE DOOR WITHOUT TRACK

A 2x4 on its side is convenient for setting an ideal
door-to-rail distance.

• Remove foam packaging.

• Raise the opener onto a stepladder. You will need help
at this point if the ladder is not tall enough.

• Open the door all the way and place a 2x4 on its side
on the top section of the door beneath the rail.

• The top of the door should be level with the top of the
motor unit. Do not position the opener more than
4" (10 cm) above this point.

INSTALLATION STEP 4

Position the Opener

Follow instructions which apply to your door type as
illustrated.

SECTIONAL DOOR OR ONE-PIECE DOOR WITH
TRACK

A 2x4 laid flat is convenient for setting an ideal
door-to-rail distance.

• Remove foam packaging.

• Raise the opener onto a stepladder. You will need help
at this point if the ladder is not tall enough.

• Open the door all the way and place a 2x4 laid flat on
the top section beneath the rail.

• If the top section or panel hits the trolley when you raise
the door, pull down on the trolley release arm to
disconnect inner and outer sections. Slide the outer
trolley toward the motor unit. The trolley can remain
disconnected until Installation Step 12 is completed.

INSTALLATION STEP 5

Hang the Opener

Three representative installations are shown. Yours may
be different. Hanging brackets should be angled (Figure 1)
to provide rigid support. On finished ceilings (Figure 2 and
Figure 3), attach a sturdy metal bracket to structural
supports before installing the opener. This bracket and
fastening hardware are not provided.

1. Measure the distance from each side of the motor unit
to the structural support.

2. Cut both pieces of the hanging bracket to required
lengths.

3. Drill 3/16" pilot holes in the structural supports.

4. Attach one end of each bracket to a support with
5/16"-18x1-7/8" lag screws.

5. Fasten the opener to the hanging brackets with
5/16"-18x7/8" hex bolts, lock washers and nuts.

6. Check to make sure the rail is centered over the door
(or in line with the header bracket if the bracket is not
centered above the door).

7. Remove the 2x4. Operate the door manually. If the door
hits the rail, raise the header bracket.

8. Grease the top and underside of the rail surface where
the trolley slides with rail grease.

NOTE: DO NOT connect power to opener at this time.

To avoid possible SERIOUS INJURY from a falling garage door
opener, fasten it SECURELY to structural supports of the
garage. Concrete anchors MUST be used if installing any
brackets into masonry.
