⚠️ Important Wind Load Advisory
The manufacturer’s specifications do not account for wind resistance. In windy areas or if your gate is solid (no airflow), wind load may exceed the system's capability and cause damage. We strongly recommend a pad-mounted system like the LiftMaster CSW24UL for such environments.
