ONE-PIECE DOOR WITH TRACK
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 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
SERIOUSLY INJURED or KILLED by a closing garage
door.
• The gap between the bottom of the garage door and
the fl oor MUST NOT exceed 1/4" (6 mm). Otherwise,
the safety reversal system may NOT work properly.
• The fl oor or the garage door MUST be repaired to
eliminate the gap.
