ONE-PIECE DOOR INSTALLATIONS
• Generally, a one-piece door does not require
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 KILLEDby aclosing garage door.
• Thegap betweenthe bottom of the garagedoor and the
floor MUST NOTexceed 1/4"(6 mm). Otherwise, the
safety reversal system may not work properly.
• Thefloor or the garage door MUSTbe repairedto
eliminate the gap.
