DoorKing 6500-381 Secondary Swing Gate Operator - 1/2 HP

Secondary Swing Gate Automation for Dual-Leaf Gate Systems

The DoorKing 6500-381 is a secondary swing gate operator designed specifically for use with the DoorKing 6500-080 primary operator in dual gate installations. This 1/2 horsepower tandem unit provides synchronized movement for the slave-side gate leaf, ensuring balanced and efficient operation of bi-parting gates up to 18 feet long and 700 pounds per leaf. It does not include a control board and requires a connection to the 6500-080 master operator for functionality.

Built with a durable steel frame and the same magnetic limit technology found in the primary model, the 6500-381 delivers dependable performance in residential, commercial, and industrial applications.
