MEGA ARM / MEGA ARM TOWER - Residential / Medium-Duty DC

The Mega Arm and Mega Arm Tower are DC-powered additions to the LiftMaster® family of gate operators. Designed with a 24V DC (1/2 HP equivalent) motor, these models provide exceptional starting torque and continuous operation, making them ideal for most applications. Constructed with an aluminum alloy chassis, they´re corrosion resistant and light enough for one person to carry and install. The heavy-duty motor supports 6,000 cycles per day with an operator speed of 2.5 seconds to open or close.

No power? No problem! Built-in battery backup provides seamless operation of the gate operator and all DC control and sensing devices in the event of a power loss.
