The Model 6050 and 6100 operators are designed to operate vehicular swing gates in residential and commercial applications. These operators are designed so that they can be either pad or post mounted without any costly and time consuming field modifications. You need to specify which mounting method when ordering. The unique design of these operators allows the gate arm to be attached to the bottom rail of the gate. This eliminates the need for any brackets to be welded to the face of the gate and creates an aesthetically pleasing installation.
