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 reversalsystem,

persons (particularly small children) could be SERIOUSLYINJUREDor KILLEDby a closing garage door.

•The gap betweenthe bottom of the garagedoor and the floor MUST NOTexceed 1/4" (6 ram). Otherwise, the safety reversalsystem may not work properly.

•The floor or the garagedoor MUST be repairedto eliminate the gap.
