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 LEFT HAND SIDE OR LEFT WOUND (BLACK WINDING
CONE), WHICH GOES ON THE RIGHT HAND SIDE.
IMPORTANT:
ON SINGLE SPRING APPLICATIONS, ONLY A LEFT WOUND (BLACK WINDING
CONE), IS REQUIRED.
NOTE:
The set screws used on all winding cones and cable drums are colored red. DO NOT
identify right and left hand by the set screw color.
Facing the inside of the door, lay the torsion shaft 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.
Lay the torsion spring with the red winding cone and the red cable drum at the left end of the
torsion shaft. Slide the center bracket bearing onto the torsion shaft followed by the torsion
springs and cable drums.
IMPORTANT:
THE CENTER BRACKET BEARING, TORSION SPRINGS, AND CABLE DRUMS
MUST BE POSITIONED, AS SHOWN.

Attaching Springs to Center Bracket
18
NOTE:
Refer to Package Contents / Breakdown of Parts, to determine which Center
Bracket(s) came with your door.
IMPORTANT:
THE SPRING WARNING TAG(S) SUPPLIED MUST BE SECURELY ATTACHED
TO THE STATIONARY SPRING CONE(S) IN PLAIN VIEW. SHOULD A REPLACEMENT SPRING
WARNING TAG BE REQUIRED, CONTACT WAYNE DALTON FOR FREE REPLACEMENTS.
Slide center bracket bearing into the spring. Align the stationary spring cone(s) with the holes
in the center bracket. Secure the torsion spring(s) to the center bracket with (2) 3/8” - 16 x
1-1/2” hex head bolts and (2) 3/8” - 16 nuts.

Attaching Counterbalance Lift Cables
19
Starting on the left hand side, thread the counterbalance lift cable up and around the front
side of the left hand cable drum.
IMPORTANT:
VERIFY THAT THERE ARE NO OBSTRUCTIONS IN THE TRAVEL PATH OF THE
DOOR SECTIONS OR COUNTERBALANCE LIFT CABLES.
NOTE:
Always assemble the left hand cable and cable drum first to help maintain equal cable
tension on both sides of the door.
Hook the counterbalance lift cable into the left hand cable drum. Slide the left hand cable
drum up against the left hand end bearing bracket. Counterbalance lift cable should termi-
nate at the 3 o’clock position.
NOTE:
If you have 32” radius horizontal track, then additional pre-wrapped counterbalance
lift cable than shown in the illustration is required.
Rotate the left hand drum and torsion shaft until counterbalance lift cable is taut. Now
attach locking pliers to the torsion shaft and brace locking pliers up against jamb to keep
counterbalance lift cable taut. Tighten the set screws in the drum to 14-15 ft-lbs of torque
(once set screws contact the torsion shaft, tighten screws an additional one full turn). Repeat
for right hand side.
IMPORTANT:
INSPECT EACH COUNTERBALANCE LIFT CABLE MAKING SURE IT IS SEATED
PROPERLY ONTO THE CABLE DRUM AND THAT BOTH COUNTERBALANCE LIFT CABLES HAVE
EQUAL TENSION.
CHECK COUNTERBALANCE LIFT CABLES FOR EQUAL TENSION:
1. Attach locking pliers to track above top roller.
2. Grasp cable at approximate mid-door height location.
3. Draw cable toward you about 1/2” to 1” and release, noting the response of the cable.
4. Repeat above steps for other cable.
5. Adjust cable tension as needed until right and left cables both respond the same.
