Cellar Door Opener – 18 Inch 450MM Stroke Electric Linear Actuator Max Thrust 5500N (Model 0041534-7) Choose Stroke Rod Material for Linear Actuator::Aluminum Alloy three linear actuators extend outwardThis 450mm stroke industrial linear actuator provides up to 5500 N of thrust force. Specially designed for large cellar doors, it provides pushing function only with no pulling function. When the linear actuator is in the fully retracted state, if there is a power outage, the linear actuator can be manually pulled out or retracted to open or close the cellar door manually. When the linear actuator is in the extended state, if there is a power outage,
