IF YOU HAVE ANGLE MOUNT VERTICAL TRACK ASSEMBLIES:
To install horizontal track,
place the top rail end over the top track roller of the top section. Align the bottom rail end of
the horizontal track with the top of the vertical track. Tighten the bottom rail of the horizontal
track to the angle mount with (2) 1/4” - 20 x 9/16” track bolts and (2) 1/4” - 20 flange hex
nuts.

Next level the horizontal track assembly and bolt the top rail of the horizontal track to the
encountered slot in the flag angle / angle mount using (1) 1/4” - 20 x 9/16” track bolt, (1)
1/4” - 20 flange hex nut and (1) 5/16” washer.
NOTE:
If you have angle mount, bolt the top rail of the horizontal track to the encountered
slots in the angle mount using (2) 3/8” - 16 x 3/4” truss head bolts, (2) 3/8” - 16 hex nuts.
Repeat for other side.

IMPORTANT:
FAILURE TO REMOVE NAIL BEFORE ATTEMPTING TO RAISE DOOR COULD

INSTALLATION INSTRUCTIONS
Attaching End Bearing Brackets
16
NOTE:
Right and left hand is always determined from inside the garage looking out.
NOTE:
Identify the end bearing brackets supplied with your door. Refer to Illustrations below,
Package Contents or Breakdown of Parts, to determine which end bearing brackets you have.
NOTE:
End bearing brackets are right and left hand.
NOTE:
Prior to fastening end bearing brackets to the jamb, pilot drill using a 3/16” drill bit.
Align the bottom edge of left end bearing bracket with the top edge of the flag angle. Main-
taining this alignment, also align the right edge of the end bearing bracket with the right edge
of the flag angle. Secure the end bearing bracket to the jamb using (3) 5/16” x 1-5/8” lag
screws, as shown. Repeat same process for the other side.

x 3/4” truss head bolt and (1) 3/8” - 16 nut. Secure the left hand end bearing bracket to the
jamb using (3) 5/16” x 1-5/8” lag screws. Repeat same process for the other side.

Attaching Center Bracket to Wall
17
NOTE:
Refer to Package Contents / Parts Breakdown, to determine if your door came with a
coupler assembly. If your door came with a coupler assembly, the mounting surface needs to
be a minimum of 17” wide. The two center bearing brackets will need to be spaced 12” to
14” apart at the center of the door, as shown.
NOTE:
Prior to fastening center bracket(s) to the header, pilot drill using a 3/16” drill bit.
NOTE:
If your door came with (4) springs, each of the outer springs mounting surface will
need to be a minimum of 3” wide.
NOTE:
If needed, measure the diameter of your springs. If you have a one piece shaft with
3-3/4” diameter springs, they do not share center brackets and do not have a coupler as-
sembly.
First, locate the center of the door. Mark a vertical pencil line on the mounting surface above
the door, at the center. Measure from the center of the bearing, in one of the end bearing
brackets, downwards, to the top the door. Using that measurement, measure that distance
upwards from the top of the door to the mounting surface and mark a horizontal pencil line
which intersects the vertical pencil line.
IF YOUR DOOR DID NOT COME WITH A CENTER COUPLER ASSEMBLY OR USES TOR-
SION SPRINGS LESS THAN 3-3/4” ID:
Mark a vertical pencil line on the mounting surface
above the door, at the center. Align the edge of the center bracket with the vertical pencil
line and the center of the center bracket with the horizontal pencil line; this is to ensure the
torsion shaft is level between the center and end bearing brackets.
NOTE:
On some single spring doors, the spring can be longer than half the opening width. If
your spring is longer, then the center bracket must be mounted off center for the spring to fit
properly. Measure spring length adding room for spring growth during winding, to determine
appropriate center bracket location.
IF YOUR DOOR DID COME WITH A CENTER COUPLER ASSEMBLY OR 3-3/4” ID TOR-
SION SPRINGS:
Mark a vertical pencil line on the mounting surface above the door, at the
center. Split the difference up and position the (2) center bearing brackets apart from each
other. Mark two vertical pencil lines, one for each center bearing bracket onto the mounting
surface above the door.
NOTE:
If your door came with a center coupler assembly or if it utilizes 3-3/4” springs, the
springs will not share a center bracket.
NOTE:
If your door has (4) springs, split the distance between the center of the door and the
end bracket on each side to locate the intermediate center brackets.
Attach the center bracket(s) to the mounting surface, using 5/16” RED HEAD lag screws, as
shown.
IMPORTANT:
USE A 5/16” X 2-1/2” RED HEAD LAG SCREW INSTEAD OF THE 5/16” X
1-5/8” RED HEAD LAG SCREW IF MOUNTING SURFACE IS COVERED BY DRYWALL. THE LAG
SCREW MUST BE ATTACHED THROUGH THE BOTTOM HOLE OF THE CENTER BRACKET(S).
