We offer a complete line of Liftmaster swing gate actuator arms like the LA400 and LA500 systems. The latest versions offer the ability to monitor, open and close your gate with your smart phone or computer with the free Liftmaster MyQ app. These arms are also available in solar powered swing gate operator packages to allow you to automate your gates in remote applications. These arm style gate operators should not be used on uphill swinging gates or over sized gates.
