STRUCTURAL SUPPORT (STUD) ON THE HEADER WALL.

WARNING
STEP 1:
Mounting the Front
Bracket — Mark a vertical centerline
on the header above the door. By
manually raising the door, determine
the high arc of the door’s travel (see
illustrations on page 4) and using a
level, transfer this measurement to
the header (see illustration at left).
Draw a horizontal line, crossing the
previously drawn centerline, at this
point. Install the Front Mounting
Bracket securely with the lag screws
as illustrated below. If necessary,
reinforce the header with steel angle
iron or wood to ensure a secure
mount.
STEP 2
: Raise the Tee Rail so that the
Front Idler Bracket and Front Mounting
Bracket align. Insert bolt and tighten nut
loosely for now. Later in the installation, this
nut must be tightened securely.
