reinforcement,
if your door is lightweight, refer to the
information relating to sectional doors in installation
Step 11.
• Depending on your door's construction, you may need
additional mounting hardware for the door bracket
(Step 11).
Without a properly working safety reversal system, persons
(particularly small children) could be SERIOUSLYINJURED
or KILLED by a closing garage door.
•
The gap between the bottom of the garage door and the
floor MUST NOT exceed1/4" (6 mm). Otherwise, the safety
reversal system may NOTwork properly.
•
The floor or the garage door MUST be repairedto eliminate
the gap.
