STEP 9a HI-LIFT TRACK
Connect vertical hi-lift track to top of existing vertical track
with 1/4”x 5/8” truss head machine screws. Set track plumb
and fasten to jamb in the same manner as the vertical track
previously installed in Step 4. Attach bearing brackets to the
horizontal angles with 3/8” x 3/4” bolts & nuts. Form rope
loops to a convenient overhead structural member and insert
horizontal tracks through them, then attach bottom of the
curved portions of track to the top of the vertical tracks at the
splice brackets with 1/4” x 5/8” truss head machine screws
and nuts. Head of machine srews should be to inside of the
track (see Figure 9a). Using a level, strike a plumb line from
the inside ot the splice bracket to the inside of the horizontal
angle on each side. Place outside edges of bearing brackets
against the plumb lines and attach
brackets securely to the wall
(see Figure 9a).
STEP 9b VERTICAL LIFT TRACK
Place upper vertical track on top of lower vertical track.
Plumb track and attach to wall in same manner as lower
vertical tracks. Heads of machine screws should be to inside
of the tracks as shown in Figure 9b. (Jamb fasteners must
be installed with no more than 48” between each fastener.)
Now set bearing brackets against the plumb lines and attach
brackets securely to the track and wall.
STEP 10
HORIZONTAL TRACK SUPPORT
Replace temporary support hangers with steel support angle
(not supplied). Install sway braces only after checking the
horizontal track with a tape measure or spacing bar to verify
that they are parallel. Important: steel support or other means
must be strong enough to support full door weight and must
be attached to a structurally sound member.
Note: a center horizontal track support is required for doors
larger than 12’-1” in height (see Figure 1 Item A on page 1).
STEP 11 TOP BRACKETS
Place top section in position. With rollers inserted in the
sleeves of top roller brackets, bolt brackets to section
through holes provided, utilizing self-tapping screws. Adjust
bracket slide so top section is perfectly vertical and tighten
adjusting bolt securely. Attach top leaves of hinges from the
preceding section. Check tracks for proper clearance and
permanently secure all fasteners.
