Fasten The Door Bracket - Craftsman 139.5399 Owner's Manual

INSTALLATION STEP 11

Fasten the Door Bracket

Follow instructions which apply to your door type
as illustrated below or on the following page.
A horizontal reinforcement brace should be long
enough to be secured to two vertical supports. A
vertical reinforcement brace should cover the
height of the top panel.
The illustration shows one piece of angle iron as the
horizontal brace. For the vertical brace, two pieces of
angle iron are used to create a "U"-shaped support
(Figure 1). The best solution is to check with your
garage door manufacturer for an opener installation
door reinforcement kit.
NOTE: Many vertical brace installations provide for
direct attachment of the clevis pin and door arm. In
this case you will not need the door bracket; proceed
to Installation Step 12.
SECTIONAL DOORS
• Center the door bracket on the previously marked
vertical centerline used for the header bracket
installation. Note correct UP placement, as
stamped inside the bracket (Figure 2).
• Position the bracket on the face of the door within
the following limits:
A) The top edge of the bracket 2"-4" (5 cm - 10 cm)
below the top edge of the door.
B) The top edge of the bracket directly below any
structural support across the top of the door.

ment but does need top and bottom fastening holes
for the door bracket, fasten as shown in Figure 2.

is needed for lightweight garage doors
(fiberglass, aluminum, steel, doors with
