FASTEN 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 (1)
using the two 8mm x 13mm (1/4"-14x5/8") self-threading
screws (2). (Figure 2A)
• Alternately, use two 8mm (5/16") bolts (3), lock washers (4) and
nuts (5). (Figure 2B)
Metal, insulated or light weight factory reinforced doors:
• Drill 4.5mm (3/16") fastening holes. Secure the door bracket (1)
using the self-threading screws 8mm x 13mm (2). (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") (6) carriage bolts, lock washers and
nuts. (Figure 4)
NOTE:
The 8mm x 13mm (1/4"-
14x5/8") (2) self-threading screws are
not intended for use on wood doors.
