Liftmaster HDLGARM Heavy Duty Long Swing Arm

Product Description

The LIFTMASTER HDLGARM is a heavy duty long swing arm designed for use with LiftMaster gate controller systems. This component provides the mechanical linkage required to translate actuator movement into gate motion, making it a critical part of automated swing gate installations. Built to handle demanding duty cycles, the long swing arm configuration accommodates gates requiring extended reach from the actuator mounting point. It is typically installed by licensed gate automation technicians or experienced fence and access control contractors.

The HDLGARM is suited for residential and light commercial swing gate automation applications where a standard-length arm does not provide adequate reach or leverage. The heavy duty construction makes it appropriate for heavier gate panels or installations with longer pivot-to-hinge distances. It is sold as a single unit and is intended as either an OEM replacement component or an original installation part within compatible LiftMaster gate operator setups.

Key Features

• Heavy duty construction for demanding swing gate applications
• Long arm configuration provides extended reach for gates with greater pivot-to-hinge distances
• OEM-style component for reliable fit and function within LiftMaster gate systems
• Sold as a single unit for direct replacement or new installation use

Compatibility

Designed as an OEM-style replacement or installation component for LiftMaster gate controller systems requiring a heavy duty long swing arm.

Installation Notes

Installation should be performed by a qualified gate automation technician or licensed contractor familiar with swing gate operator systems. Disconnect and lock out all power to the gate operator before removing or installing any mechanical arm components. Verify that mounting hardware is properly torqued and that the arm geometry aligns with the gate operator manufacturer guidelines before restoring power. Local codes and the manufacturer installation instructions should be consulted prior to beginning work.
