ONE-PIECE DOOR INSTALLATIONS
l
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.
l
Depending on your door’s construction, you may need
additional mounting hardware for the door bracket (Step 8).
Without a properly working safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
l
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.
l
The floor or the garage door MUST be repaired to eliminate
the gap.
