IMPORTANT! Spacing between the left hand and the right end bearing brack- ets must be door width plus
Important: Do not support the weight of the door on any part of the rear or center back hangs that cantilevers 4” or more beyond a sound framing member.
Note: If rear or center back hangs are to be installed over drywall, use (2) 5/16” x 2” hex head lag screws and make sure lag screws engage into solid structural lumber.

IMPORTANT: RIGHT AND LEFT AND IS ALWAYS DETERMINED FROM INSIDE THE GARAGE LOOKING OUT.
NOTE: The set screws used on all torsion counterbalance winding cones and cable drums, are now colored red. DO NOT identify right and left hand by the set screw color.
NOTE: Depending on your door, there may be letters stenciled onto the spring which refer to right hand wound and left hand wound.
IMPORTANT: Identify the springs provided as either right hand wound (red winding cone), which goes on the RIGHT HAND SIDE or left hand wound (black winding cone), which goes on the LEFT HAND SIDE.
IMPORTANT: Reference the illustrations for proper spring positioning when more than 2 springs are provided.
IMPORTANT: On single spring applications, only a left hand wound (black winding cone), which goes on the LEFT HAND SIDE is required.
Facing the inside of the door, either lay the torsion shaft/torsion keyed shaft on the floor or lay the (2) torsion keyed shafts on the floor, one torsion keyed shaft on the left hand side and the other torsion keyed shaft on the right hand side.
IMPORTANT: Depending on your door application, use one of the three illus- tration’s, shown below to assemble your torsion counterbalance system.
1.Lay the torsion spring with the black winding cone and the black cable drum at the left end of the torsion shaft or the torsion keyed shaft. Lay the torsion spring with the red winding cone and the red cable drum at the right end of the torsion shaft or the torsion keyed shaft. Next, lay the center bearing bracket, the center bearing or the oval bearing at the center of the torsion shaft/torsion keyed shaft.
