Liftmaster LA400DCS Actuator Arm Secondary

Product Description

The LIFTMASTER LA400DCS is a secondary actuator arm designed for use in automated gate control systems. This component provides the mechanical linkage needed to drive or assist in the movement of a gate panel, working in coordination with a primary actuator assembly. It is built for gate controller applications where dependable, repeatable arm travel is required. Licensed gate automation technicians and commercial access control installers are the primary trades that source and install this part.

This secondary actuator arm is intended for gate controller installations where a dual-arm configuration is required, such as systems serving driveways, commercial entryways, or restricted-access lanes. The LA400DCS works within the LIFTMASTER LA400 actuator system and is sold as a single unit. It is suited for both new installations and replacement service on existing dual-arm gate operator setups.

Key Features

Installation Notes

Installation should be performed by a qualified gate automation technician or licensed access control professional. Before servicing or replacing any actuator arm, disconnect power to the gate operator and ensure the gate panel is secured against unintended movement. Follow the manufacturer installation documentation for proper mounting and arm geometry. Local codes and UL 325 requirements for gate operator safety devices should be observed during any gate system service.
