ONE-PIECE DOOR INSTALLATIONS
• Generally, a one-piece door does not require
reinforcement. If your door is lightweight, you can
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).
• The gap between the bottom of the garage door
and the floor cannot exceed 6mm. Otherwise, the
safety reverse system may not work properly. See
Adjustment Step 3. The floor or the door should be
repaired.
