For additional mounting options see accessories
page.
1. Close the garage door completely.

bar. Ensure that the collar does not touch the bearing
plate. Check to make sure the mounting bracket is
located on a solid surface such as wood, concrete or
door/flag bracket. Snug collar screws to help assure
proper alignment of operator. Mark the bracket holes. It
may be necessary to cut the torsion bar if it is too long
or damaged.

opener. Drill 3/16" pilot holes at the marked locations.
Drill through steel plate if needed.
4. Reinstall the opener by sliding the collar over the torsion
bar until pilot holes align with bracket. Securely tighten
collar screws that attach to the torsion bar to 12-14 ft./
lbs. of torque. Securely tighten both set screws firmly,
without damaging the motor unit.
NOTE:
To allow access to the set screws it may be
necessary to raise the door slightly in order to rotate the
torsion bar.
5. Fasten bracket securely with 14-10x1-7/8" screws.
Tighten all mounting bracket hardware.
NOTE:
The motor unit does not have to be flush to wall.
6. Use a staple to secure the antenna wire to prevent
antenna from being entangled in a door roller.
