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.

With assistance, pick up the torsion spring assembly and slide one end of the torsion shaft
/ torsion keyed shaft through one end bearing bracket. Lay the middle of the torsion shaft /
torsion keyed shaft into the center bracket. Slide the other end of the torsion shaft / torsion
keyed shaft into the other end bearing bracket. Position the torsion shaft / torsion keyed shaft
so that equal amounts of the shaft extend from each end bearing bracket.
