I used two for the sides and two for the top & bottom locks, all operating in parallel. These only have a 4' stroke, but the operation is identical on all units. Love the power and speed of the motors, they operate until the end of the stroke, then will stop. Reverse is the same, I plan to use a remote-control device to operate the movement. I would and will use these motors again on future projects. Review: Works great easy to install - The actuator works perfectly. Just wish it would go a little faster but it does exactly what I needed it to do without hesitation. Great product and water proof so far ## Features - Specification：Voltage:12V DC; Stroke Length:8"(200mm), Retracted length: 13"(330mm), Extended Length:20.87"(530mm); No load speed: 0.31"/sec (8mm/s), Maximum Load:440lbs(2000N); Maximum current draw:5A; Duty Cycle:10%, Working power should reach 40W-50W - Durable & Robust Material：Crafted from high-quality aluminum alloy, this linear actuator with corrosion resistance,heat dissipation and high hardness,it can extend the service life,and the black powder-coated surface of the actuator can enhance corrosion resistance - Powerful & Long-Lasting Upgraded Motor：JQDML linear motion actuator with high-performance motor provides 440 lbs max thrust & 330 lbs max pull, ideal for heavy-duty use.Built-in screws ensure strong rustproof & waterproof performance, while reducing exposed fasteners and lowering maintenance difficulty - Quiet Operation & Stable Base Design：Low-noise design (≤50dB),with a premium plastic turbine that resists oxidation, extends service life, and ensures quiet movement.Upgraded four-corner fixed base, which resists loosening and breakage, enhances stability and ensures operational safety - Reliable Operation & Easy to Install：Equipped with a limit switch,it can automatically stop the motor when reaching both ends, and its strong self-locking function allows it to stay in any position,preventing motor burnout and load slipping.The linear actuator comes with mounting brackets for quick, easy assembly.
