FAILURE TO RE-ATTACH HORIZONTAL
TRACKS TO THE SUPPORT BEFORE
OPENING DOOR CAN CAUSE DOOR
TO FALL FROM OVERHEAD POSITION,
POSSIBLY CAUSING SEVERE OR FATAL
INJURY.
NOTE:
Door must be in the fully closed
position.
If the vertical track was raised then the
horizontal track will need to be adjusted.
Remove bolt securing back of horizontal
track to the perforated angle and reposition
horizontal track UP 1” (25mm) from it’s
original position.
Re-attach the horizontal track to the
perforated angle with the same
bolt and nut.
Assemble bolt and nut from the direction
shown so bolt will extend inside of track.

Adjustment (If Required)
Remove the (3) self-tapping screws from
the top bracket.
Align the top hole of the top bracket with
the #2 hole in the end cap and re-attach the
top bracket to the end cap with the same
three self-tapping screws. It may be
necessary to relocate the top strut (if
installed) to correctly place the top bracket
in its new location.
Re-align the top roller in the track by
moving top bracket slide out until door
section is straight up and down. Tighten the
flange nut.
Repeat for opposite side.
