NOTE: Depending on your door, you may have Quick Install Flag Angles, Fully Adjustable
Flag Angles or you may have Riveted Vertical Track Assemblies. Refer to Package Contents /
Breakdown of Parts, to determine which Flag Angles / Vertical Track Assemblies you have.
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.
Starting on the left hand side of the bottom section, remove the nail. Position the left hand
vertical track assembly over the track rollers of the bottom section. Make sure the counter-
balance lift cable is located between the track rollers and the door jamb.
NOTE: Drill 3/16” pilot holes into door jamb for the lag screws.
Loosely fasten jamb brackets and flag angle to the jamb using 5/16” x 1-5/8” lag screws.
Tighten lag screws, securing the bottom jamb bracket to jamb, maintain 3/8” to 5/8” spac-
ing, between the bottom section and vertical track. Hang counterbalance lift cable over flag
angle. Repeat same process for other side.
