High Lift Track
Some smaller high lift doors will come with verti-
cal tracks in one piece plus the horizontal tracks.
Larger high lift doors will have the vertical track in
two pieces plus the horizontals. Follow the vertical
track information (Step 1, page 16) for the lower
part of the track from the floor to the top of the
door. Starting at the the door, plumb one vertical
track and lag or screw it to the wall all the way up.
Measure the width of the tracks at the top of the
door and set the very top of the second track at
the exact same distance. Finish fastening the
center of the vertical track, making sure the
distance between the tracks is equal from the top
of the door on up. Attach the horizontal tracks
using
1
/4" x
5
/8" track bolts and
3
/8" x
3
/4" carriage
bolts to attach the horizontal angle. Rig a tempo-
rary rope to support back of horizontal tracks.
They should be level (parallel) to 1" higher in
back. Attach the bearing plates as shown in
Figure 15-T. Install top section to other sections.
(FIG. 9-S, page 12) See spring winding information
for installing and winding springs.

IMPORTANT: Do not cut cables. It may seem
like the cables are too long, but they are not. Wind
the extra cable onto the drums.
After the springs have been installed and wound,
raise the door so that only the two top sections
are in the horizontal track. Secure the door in
place with locking pliers on track above a roller
making sure it can’t be raised. Backhang doors as
shown in Figure 17-T. Any door with a horizontal
track 11' 6" long or longer requires two backhangs
on each horizontal track. (FIG.17-T) (See impor-
tant note page 17 for additional backhang require-
ments.) Attach spring bumpers as shown in
Figure 16-T. They will keep the door from coming
out of the back of the tracks. Push the door
against the stop or steel jambs and tighten track
bolts. Adjust top brackets. (FIG. 9-S, page 12)
Install inside slide lock or lock bars after springs
are wound. (FIG. 7-S & 8-S, page 12) Nail door
stop in place if applicable.
