For Dual Swing Gates up to 18 feet long or 850 pounds per leaf.
Our most popular dual gate opener, the Mighty Mule 502 Dual Gate Opener (FM502) has NEW commercial features rarely found in a do-it-yourself gate opening kit.

The Mighty Mule 502 Dual Gate Opener (FM502) is a heavy-duty, commercial-grade unit, yet very easy to install. It has upgraded commercial features such as soft start and soft stop that will extend the life of your gate hardware and gate opener. Another feature is the extra large control box that is pre-wired for an optional second battery (We highly recommend a second battery for solar applications). All these advanced features are contained in a easy to install, Do-it-Yourself kit. The Mighty Mule kit includes a helpful installation video and detailed manual so you can install it yourself!

Designed for gates that open into or away from the property. Note: push-to-open applications (away from the property) require 2 push-to-open brackets: 347IH located here. Use on solid (wood) gates is not recommended as solid-surface gates have high wind resistance. If the wind is strong enough, the opener will obstruct and stop. For solid gates please see our GTO/PRO SW4000 series.

The Mighty Mule 502 Dual Gate Opener is compatible with all accessories including solar panels
