Identify the type and height of your garage door.
Survey your garage area to see if any of the
conditions below apply to your installation. Additional

your opener.

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 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.
