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.
