Mighty Mule® Automatic Gate Opener, Single Gate
The Mighty Mule® FM500 single swing automatic gate opener is a heavy duty, commercial grade swing gate opener that is very easy to install. This gate opener will work with gates 18 feet long or weighing up to 850 pounds. The FM500 gate opener comes in a standard Do-It-Yourself kit, which includes an installation DVD, detailed manual, battery, transmitter, all mounting hardware, and 18 V AC transformer.
The FM500 automatic gate opener features a soft start and stop when opening and closing, an adjustable auto close, an auto gate activation alert for your protections, obstruction sensing systems, as well as an extra large control box that has room for an optional second battery. (We recommend using a second battery for solar applications). The 12 Volt, DC-powered, low-voltage system is powerful, dependable, durable, and is ideal for gates that open into the property or with gates opening out from the property using a Push-To-Open Bracket FM148 (sold separately).
Low Voltage wire (RB509) is required for most installations (sold separately). The Mighty Mule® FM500 is the best-selling DIY gate opener in America, and it is known for its ability to work well on a wide variety of swing gates, chain link fences, tube gates, or wrought iron.
