ONE-PIECEDOORINSTALLATIONS
• 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.
• Dependingon your door's construction, you may need
additional mounting hardwarefor the door bracket (Step 11).
Without a properly working safety reversalsystem, persons
(particularly small children) could be SERIOUSLYINJUREDor
KILLEDby a closing garage door.
• The gap betweenthe bottom of the garagedoor and the
floor MUSTNOTexceed1/4" (6 mm). Otherwise,the safety
reversalsystem may NOTwork properly.
• The floor or the garagedoor MUST be repairedto eliminate
the gap.
