To prevent damage to garage door, reinforce inside of
door with angle iron both vertically and horizontally.
Mark and Drill 3/16" Holes
Position the door bracket on
the face of the door within the
following limits:
1. The top edge of the bracket
2"-4" (5-10 cm) below the
top edge of the door.
2. The top edge of the bracket
directly below any structural
support across the top of the
door.
Horizontal and vertical reinforcement (not
provided) is needed for light weight garage doors
(fi berglass, aluminum, steel, doors with glass
panel, etc.).
A horizontal reinforcement brace should be long
enough to be secured to two or three vertical
supports. A vertical reinforcement brace should
cover the height of the top panel. Contact your
door manufacturer for more information regarding
reinforcement of your door.
Many door reinforcement kits provide for direct
attachment of the clevis pin and door arm. In this
case, you will not need the door bracket; proceed
to Connect Door Arm to Trolley section.
