came with your door.

NOTE:

Prior to fastening center bracket(s) into the door jamb, pilot drill using a 3/16” drill bit.

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:

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 single 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 to determine appropriate center bracket location.

If your door did come with a center coupler assembly or 3-3/4” ID Torsion 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 each of the center bracket(s) to the mounting surface, using 5/16” RED HEAD lag

screws, as shown.

IMPORTANT:

THE 5/16” RED HEAD LAG SCREWS MUST BE ATTACHED TO THE CENTER

BRACKET(S).

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).

Torsion Spring Assembly

Tools Required: 3/8” Wrench, 9/16” Wrench, Step ladder, Tape measure, Safety

glasses, Leather gloves

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 HAND WOUND

(RED WINDING CONE), WHICH GOES ON THE LEFT HAND SIDE OR LEFT HAND WOUND

(BLACK WINDING CONE), WHICH GOES ON THE RIGHT HAND SIDE.

IMPORTANT:

ON SINGLE SPRING APPLICATIONS, ONLY A LEFT HAND WOUND (BLACK

WINDING CONE), WHICH GOES ON THE RIGHT HAND SIDE IS REQUIRED.

NOTE:

The set screws used on all torsion winding cones and cable drums are now 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 / torsion keyed shaft on the floor. Lay the

torsion spring with the black winding cone and the black cable drum at the right end of the

torsion shaft / torsion keyed shaft. Lay the torsion spring with the red winding cone and the

red cable drum at the left end of the torsion shaft / torsion keyed shaft.
Slide the center bracket bearing / center bracket bushing onto the torsion shaft / torsion

keyed shaft followed by the torsion springs and cable drums.

IMPORTANT:

THE CENTER BRACKET BEARING / CENTER BRACKET BUSHING, TORSION

SPRINGS, AND CABLE DRUMS MUST BE POSITIONED, AS SHOWN.
