MOUNT OPERATOR TO CEILING
Method A For open ceilings with exposed
joist, drill 5/32" pilot holes and secure
PERFORATED HANGING STRAPS (NOT-
included) to joist using 5/16" x 1-3/4" lag
screws. Raise operator unit so that there
is sufficient clearance between door and
rail. Cut and/or bend mounting straps as
needed to align with the operator and to
level the rail. Secure operator to mounting
straps using 5/16"-18 x 3/4" bolts and nuts.
Ensure operator is centered with the door
and remove the 2 x 4 board and/or other
protective material and close the garage
door.
Method B For finished or unfinished ceilings,
attach perforated angle (not supplied) to
joists using 5/16" x 1-3/4" lag screws and
secure mounting straps to the perforated
angle with 5/16"-18 bolts and nuts (not
supplied). Raise operator so that there
is sufficient clearance between door and
rail. Cut and/or bend mounting straps as
needed to align with the operator and to
level the rail. Secure operator to mounting
straps using 5/16"-18 x 3/4" bolts and nuts.
Ensure operator is centered with the door
and remove the 2 x 4 board and/or other
protective material and close the garage
door.
