PLANNING (CONTINUED)
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 8.
•
Depending on your door’s construction, you may need
additional mounting hardware for the door bracket
(Installation Step 8).
Without a properly installed safety reversing sensor, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
•
The gap between the bottom of the garage door and the floor
MUST NOT exceed 1/4" (6 mm). Otherwise, the safety
reversal system may NOT work properly.
•
The floor or the garage door MUST be repaired to eliminate
the gap.
