Fasten The Door Bracket - Craftsman 139.53965SRT Manual Del Propietário

INSTALLATION STEP 12
Fasten Door Bracket
Follow instructions which apply to your door type
as illustrated below or on the following page.
A horizontal brace should be long enough to be
secured to 2 vertical supports. A vertical 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, 2 pieces of
angle iron are used to create a "U"-shaped support.
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 Step 13.
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.
• Position the bracket on the face of the door within
the following limits:
A) The top edge of the bracket 2"-4" 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.
To prevent damage to garage door, reinforce inside of
door with angle iron both vertically and horizontally.
