*If your garage door requires a center post to be installed during a wind event, the LiftMaster Automatic Garage Door Lock cannot be used to replace that system. Our LiftMaster system requires your garage door meet all wind-load specifications and guidelines provided by your local building codes. For further information and to determine if your garage door qualifies for our approved, hurricane-ready solutions, please contact your LiftMaster Sales Representative or garage door opener manufacturer.
