LiftMaster/Chamberlain Replacement Model - LJ8900W/LJ8950W/MJ5011U Commercial Door Operator for Sectional & Rolling Doors

LiftMaster's Commercial Door Operators cater to the specific needs of facilities requiring reliable, secure, and efficient door control solutions. Whether your facility demands a light-duty operator like the LJ8900W and LJ8950W or a more robust medium-duty option like the MJ5011U, LiftMaster provides advanced technology to enhance security, operational efficiency, and monitoring capabilities.

The LiftMaster LJ8900W is designed for light-duty sectional doors, offering a rated duty cycle of 10 cycles per hour and up to 25 cycles per day. The LJ8950W is similarly suited for light-duty rolling doors and grilles, providing smooth operation with a soft start/stop DC motor that reduces hardware wear and tear. Both models come with built-in Wi-Fi®, enabling seamless integration with myQ Smart Facility Access, which delivers real-time data and analytics to improve efficiency and reduce costs.

For facilities needing a medium-duty solution, the LiftMaster MJ5011U is ideal for high and vertical lift sectional doors, as well as small rolling doors and grilles. This operator supports up to 12 cycles per hour and a maximum of 50 cycles per day. It includes a powerful 1/2 HP motor and features a 3-Channel Security+® Receiver that can program up to 20 remote controls. The Timer-to-Close function, programmable between 5 to 60 seconds, ensures doors close automatically, enhancing security and energy efficiency.
