Max Thrust 3500N Cellar Door Linear Actuator IP67 Rating Waterproof & Low Noise – 12 Inch 300MM Stroke (Model 0041938-7) Choose Stroke Rod Material for Linear Actuator::Stainless Steel 1) When all linear actuatorsThis is an IP67 waterproof electric linear actuator with a 300 mm stroke, specially designed for cellar door applications. It delivers a maximum thrust of 3500 N 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,
