1/2 inch, 7/16 inch sockets and ratchet wrench,
adjustable wrench or 1/2 inch and 7/16 inch open-

Additional Materials Required (not supplied) - perfo-
rated angle straps, 5/16 x 1-1/2 inch lag screws,
5/16-18 x 3/4 inch bolts, nuts and lock washers.
Align the center of the rail assembly with centerline
on top section of garage door marked in Step 3. This
will ensure rail will be parallel to direction of door
travel.
Using perforated angles hang opener end from
ceiling joists as illustrated. Be sure horizontal angle
spans at least three joists.
Recommended distances from header wall to
horizontal angle is shown below:
7 foot rail – 122 inches
8 foot rail – 134 inches
10 foot rail – 158 inches
Length of vertical angles is determined by adding
1-1/2 to 2 inches to distance measured from ceiling or
joists to wall hanger bracket in Step 3. An additional
angle brace is recommended to ensure a rigid instal-
lation.
Pilot drill into joists with 1/4 inch drill and fasten
horizontal perforated angle to joists with 5/16 x 1-1/2
inch lag screws. Vertical straps are attached to
horizontal straps with appropriate bolts, nuts and
washers. Attach opener to vertical straps with 5/16-18
x 3/4 inch bolts, nuts and lock washers. Before tight-
ening 5/16 hanger bolts be sure rail is level.
When opener is securely attached to perforated
angles remove 2” x 4” from top of door (if used) and
close door.
Opener rail should be aligned perpendicular to the
garage door when properly installed. There should be
no sagging of rail in any direction.
