Liftmaster LA500DC Primary Actuator Arm Gate Controller

Product Description

The LIFTMASTER LA500DC is a primary actuator arm designed for automated gate control applications. This unit serves as the main drive arm in a swing gate operator system, converting motor output into the mechanical force needed to open and close a gate panel. It is built for integration into gate access systems where reliable, repeatable actuation is required. Licensed gate automation technicians and access control installers are the primary trade professionals who specify, install, and service this component.

The LA500DC primary actuator arm is used in residential and light commercial swing gate installations. It is suited for applications where a motorized arm operator is mounted to a post or pillar and connected directly to the gate leaf. This component is the main structural and mechanical link between the operator motor and the gate panel, making correct sizing and secure mounting critical to system performance.

Key Features

• Primary actuator arm provides the main mechanical drive linkage for swing gate operation
• Designed for use in automated gate operator systems requiring direct arm actuation
• Sold as an individual unit, one actuator arm per package
• Compatible with the LA500DC gate operator platform

Compatibility

Designed as an OEM-style replacement or primary component for use with the LIFTMASTER LA500DC swing gate operator system.

Installation Notes

Installation should be performed by a qualified gate automation technician familiar with low-voltage access control and mechanical gate systems. Disconnect and lock out all power to the gate operator before removing or installing the actuator arm. Secure all mounting hardware to manufacturer specifications using appropriate fasteners for the post and gate material. Verify travel limits and obstruction sensing are correctly configured before returning the system to service.
