IMPORTANT: If your door is to be installed prior to a finishing construction of the building’s floor, the vertical tracks and the door bottom section assembly should be installed such that when the floor is constructed, no door or track parts are trapped in the floor construction.
Important: The tops of the vertical tracks must be level from side to side. If the bottom section was shimmed to level it, the vertical track on the shimmed side must be raised the height of the shim.
Position the left hand vertical track assembly / wall angle track assembly over the track rollers of the bottom section. Make sure the counterbalance lift cable is located between the track rollers and the door jamb. Drill 3/16” pilot holes into the door jamb for the lag screws.
For flag angle track assemblies:
Loosely fasten jamb brackets and flag angle to the jamb using 5/16” x
For wall angle track assembly:
Loosely fasten wall angle to the jamb using 5/16” x
If you have 2” vertical tracks:
Tighten lag screws, securing the bottom jamb bracket/bottom slot to jamb, maintain 3/8” to 5/8” spacing, between the bottom section and vertical track.
