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.
NOTE:
Make sure the counterbalance lift cable is located between the track rollers and the
door jamb.
