Fibreglass, aluminum or lightweight steel garage doors
WILL REQUIRE reinforcement BEFORE installation of
door bracket. To prevent damage to garage doors
reinforce inside of door with angle iron both vertically
and horizontally.
W WARN ARNING ING
CAUTION CAUTION 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 or three vertical
supports. A vertical reinforcement brace should
cover the height of the top panel.
Figure 1 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.
The best solution is to check with your garage door
manufacturer for an opener installation door
reinforcement kit.
NOTE: 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 Step 12.
SECTIONAL DOORS
1. Centre the door bracket on the previously marked
vertical centreline used for the header bracket
installation. Note correct UP placement, as
stamped inside the bracket.
2. Position the top edge of the bracket 50mm -
100mm (2"-4") below the top edge of the door, OR
directly below any structural support across the top
of the door.
3. Mark, drill holes and install as follows, depending
on your door’s construction:
Metal or light weight doors using a vertical angle
iron brace between the door panel support and
the door bracket:
• Drill 4.5mm (3/16") fastening holes. Secure the
door bracket using the two 8mm x 13mm (1/4"-
14x5/8") self-threading screws. (Figure 2A)
• Alternately, use two 8mm (5/16") bolts, lock
washers and nuts. (Figure 2B)
Metal, insulated or light weight factory reinforced
doors:
• Drill 4.5mm (3/16") fastening holes. Secure the
door bracket using the self-threading screws.
(Figure 3)
Wood Doors:
• Use top and bottom or side to side door bracket
holes. Drill 8mm (5/16") holes through the door
and secure bracket with 8mm x 65mm (5/16"x2")
carriage bolts, lock
washers and nuts (not
provided). (Figure 4)
NOTE: The 8mm x 13mm
(1/4"-14x5/8") self-threading
screws are not intended for
use on wood doors.
