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 betweenthe bottom of the garage door and
the floor MUST NOTexceed 1/4". Otherwise, the safety
reversal system may not work properly.
• The floor or the garage door MUST be repaired to
eliminate the gap.
