Always Check the Gate’s Action
It’s very important before installing the gate operator to make sure the gate’s swing is free and level throughout the entire swing path. If the gate does not seem to operate properly, it may affect the operator performance or greatly shorten the life of the unit. The gate should also be designed so that airflow is ample to prevent wind resistance and drag.
