STEP 6. Secure the end hinges, (one side only) center hinges, and strutting ( if applicable) as previously illustrated. Locate the Lock Section (usually the second section) and insert a roller into the end hinge. Stack this section into the opening by hooking the roller in the vertical track and lowering it onto the bottom section. Insert a roller into the appropriate end hinge and insert roller into vertical track on the opposite end. Secure end hinge to the section using the

NOTE : Top section maybe installed now or may wait until the last step (installer preference)
STEP 7. Adjust the vertical track from 1/2” spacing at the bottom section to 3/4” at the top section. Refer to page 3. Permanently secure each vertical to the jambs using the following fasteners:
Steel Jambs: 5/16” x 1” self drilling and tapping screw.
Wood Jambs: 5/16” x
Precast or Block: 3/8” x 3” sleeve anchor.
The left hand vertical track assembly indicates the standard fastener spacing (Fig. K page 7).
STEP 8: Use chain or cable to temporarily 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: Torsion spring assemblies can be of several configurations depending on door size and weight. Left or right hand spring(s) must be identified by the color of the winding cone. (Refer to Fig. L and pages
Assemble torsion spring system components to applicable configuration shown on pages
WARNING: Install support brackets to solid structural members only. Do not install over dry wall or paneling.
NOTE: Use a chalk line or line level to ensure all support brackets are in line.
STEP 10: Position shaft(s) with spring system components to proper elevation, level and secure each end bracket to the horizontal reinforcing angle using (2) 3/8” x 3/4” truss bolts and nuts. Anchor the wall mounting flange of the end bracket to the jamb

Attach the spring support brackets to the pad(s) using the following fasteners:
Steel: Secure each spring support bracket using (3) 5/16” x 1”
Block Construction: Attach perforated angle 18” long to support bracket(s) using (2) 3/8” x
Secure the stationary cone(s) (dead end) to the spring support bracket(s) using 3/8” bolts and nuts. Keep spring warning tags clearly visible.
NOTE: The coupler support brackets only require (2) fasteners. The spring support brackets require (2) fasteners in the lower slot and hole, then (1) fastener in the top slot.
WARNING: Failure to use proper number of fasteners can result in sudden spring tension release, causing severe injury or death.

STEP 11: Feed the cable attached to the left hand bottom bracket up the vertical track, behind the roller shafts and secure to the left hand drum. Push the drum up against the end bearing bracket and secure to the shaft by tightening the set screws (solid shafts use 1/4” key(s) and set screws to secure drums).
Rotate drum and shaft until cable is taut, then apply vice grips to shaft, with end resting against header. This will hold cable taut and on drum. There must be at least 1/2 wrap of cable on the drum. If not, contact
If top section is not installed, do so now, before winding springs. Make sure hardware is securely attached to all sections. Carefully following spring winding instructions detailed in Fig. M on Page 10, wind spring(s), using the appropriate 1/2”, 5/8” or 3/4” diameter winding rods of sufficient length.

STEP 12: After spring(s) are wound, cautiously remove locking pliers from vertical tracks, while pushing downward on door to prevent it from raising unexpectedly, in case spring(s) were over wound. Carefully and slowly raise door, until one and a half sections are in the horizontal tracks. Lock door in this position using locking pliers attached to vertical tracks above bottom roller on one side and below bottom roller on other side of door.
Space the horizontal tracks 3/4” from section edge and level. Using
