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 SERIOUSLYINJUREDor
KILLED by a closing garage door.
• The gap between the bottom of the garage door and the
floor MUST NOTexceed 1/4" (6 mm). Otherwise, the safety
reversal system may NOTwork properly.
• The floor or the garage door MUSTbe repaired to eliminate
the gap.
