STEP 8. Installing the Horizontal Track: Use chain or cable to suspend the rear of the horizontal tracks. Secure the horizontal reinforcing angle to the wall angle using (1) 3/8” x 3/4” truss bolt and nut, then secure the horizontal track to the splice plate or flagangle using (2) track bolts and hex flange nuts.
STEP 9. Installing the Torsion Springs: Torsion spring assemblies can be of several configurations depend- ing on door size and weight. If single spring the left or right hand spring must be identified by the color of the winding cone. (Refer to fig. M and pages 11 & 12)
Slide the cable drums and the end bearing brackets onto the 1 piece shaft (tubular or solid). Slide the cable drums, end bearing brackets and coupler onto each split solid shaft and install similar to 1 piece shaft. Position the shaft to the proper elevation and secure the bearing bracket(s) to the spring pad using the proper fasteners as shown in fig.
WARNING: DO NOT INSTALL CENTER BEARING BRACKETS DIRECTLY ONTO PANELING OR DRYWALL !
NOTE: Use a chalk line or line level to ensure all bearing brackets are in line. (± 1/8”)
