Attaching Center Bracket to Wall
12
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).
IF MOUNTING SURFACE IS A 2” X 6” BOARD INSTALLED ON TOP OF MASONRY, DRILL A
CLEARANCE HOLE IN MASONRY FOR THE 5/16” X 2-1/2” RED HEAD LAG SCREWS.

Torsion Spring Assembly
13
NOTE:
Refer to the Package Contents and or Parts Breakdown to determine if your door
came with a coupler assembly.
IMPORTANT:
RIGHT AND LEFT HAND IS ALWAYS DETERMINED FROM INSIDE THE BUILDING
LOOKING OUT.
IMPORTANT:
IDENTIFY THE TORSION SPRINGS PROVIDED AS EITHER RIGHT WOUND (RED
WINDING CONE), WHICH GOES ON THE RIGHT HAND SIDE OR LEFT WOUND (BLACK WIND-
ING CONE), WHICH GOES ON THE LEFT HAND SIDE.
IMPORTANT:
ON SINGLE SPRING APPLICATIONS, ONLY A LEFT WOUND (BLACK WINDING
CONE), WHICH GOES ON THE LEFT HAND SIDE IS REQUIRED.
NOTE:
The set screws used on all torsion winding cones and cable drums are colored red.
DO NOT identify right and left hand by the set screw color.
IF YOU DON’T HAVE A COUPLER ASSEMBLY:
Facing the inside of the door, lay the torsion
shaft on the floor. Lay the torsion spring with the red winding cone at the right end of the
torsion shaft. Lay the torsion spring with the black winding cone at the left end of the torsion
shaft. Slide the center bracket bearing onto the torsion shaft followed by the torsion springs
and set collars (if applicable).
IMPORTANT:
THE CENTER BRACKET BEARING / TORSION SPRING(S) AND THE SET COL-
LARS (IF APPLICABLE) MUST BE POSITIONED, AS SHOWN.
