top fixture slides into place using (1) 1/4” - 20 x 9/16” track bolt and (1) 1/4” - 20 hex nut
through any two aligning holes.

Attaching End Bearing Brackets
14
NOTE:
Refer to Package Contents / Breakdown of Parts, to determine which End Bearing
Brackets you have.
NOTE:
Prior to fastening end bearing brackets into the door jamb, pilot drill using a 3/16”
drill bit.
IMPORTANT:
RIGHT AND LEFT HAND IS ALWAYS DETERMINED FROM INSIDE THE BUILDING
LOOKING OUT.
NOTE:
End bearing brackets are right and left hand.
DEPENDING ON WHICH END BEARING BRACKET YOU HAVE:
Either attach the left hand
end bearing bracket to the left hand flag angle or through either the end bearing bracket’s
upper / lower slots to the left hand horizontal track angle using (2) 3/8” - 16 x 3/4” truss
head bolts and (2) 3/8” - 16 nuts, as shown.

Attaching Center Bracket to Wall
15
NOTE:
Refer to Package Contents / Breakdown of Parts, to determine which Center
Bracket(s) came with your door.
NOTE:
Drill 3/16” pilot holes into header for the lag screws.
NOTE:
Refer to Package Contents / Breakdown of Parts, 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:
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 TORSION
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.
