hardware not included in the carton.
• Step 1, page 13 – Look at the wall or ceiling above the
garage door. The header bracket must be securely
fastened to structural supports.
• Step 6, page 20 – Do you have a finished ceiling in your
garage? If so, a support bracket and additional fastening
hardware (not supplied) may be required.
• Safety reversing sensor, page 16 – Depending on garage
construction, wood blocks may need to be securely
fastened to mounting locations before sensors are
installed.
• Step 14, page 17 – Alternate floor mounting of the
safety reversing sensor will require hardware that is not
provided.
• Step 12, page 25 – Generally, a one-piece door does not
require reinforcement. If your door is lightweight, you
can refer to the information relating to sectional doors
on page 24.
• Step 12, page 25 – Depending on your door's
construction, you might need additional mounting
hardware for the door bracket.
• Do you have an access door in addition to the garage
door? If not, Model 53702 Emergency Key Release is
required. See page 38.
• The gap between the bottom of the garage door and
the floor cannot exceed 1/4". Otherwise, the safety
reverse system may not work properly. See page 30.
