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. 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.
Attach the center bracket to the mounting surface, using (2) 5/16” x 1-5/8” lag screws and
(1) 5/16” x 2” tamper-resistant lag screw.
IMPORTANT: USE A 5/16” X 1-5/8” TAMPER-RESISTANT LAG SCREW INSTEAD OF THE
5/16” X 2” TAMPER-RESISTANT LAG SCREW IF MOUNTING SURFACE IS MOUNTED OVER
MASONRY. TAMPER-RESISTANT LAG SCREW MUST BE ATTACHED THROUGH THE BOTTOM
HOLE OF THE CENTER BEARING BRACKET.

IMPORTANT: RIGHT AND LEFT HAND IS ALWAYS DETERMINED FROM INSIDE THE BUILDING
LOOKING OUT.
NOTE: Identify the torsion 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.
Facing the inside of the door, lay the torsion shaft on the floor. Lay the torsion spring with the
black winding cone and the red cable drum at the left end of the torsion shaft. Lay the torsion
spring with the red winding cone and the black cable drum at the right end of the torsion
shaft.
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.
Slide the center bracket bushing onto the torsion shaft followed by the torsion springs and
cable drums.
IMPORTANT: THE CENTER BRACKET BUSHING, TORSION SPRINGS, AND CABLE DRUMS
MUST BE POSITIONED, AS SHOWN.
With assistance, pick up the torsion spring assembly and slide one end of the torsion shaft
through one end bearing bracket. Lay the middle of the torsion shaft into the center bracket.
Slide the other end of the torsion shaft into the other end bearing bracket. Position the torsion
shaft so that equal amounts of the shaft extend from each end bearing brackets.
