This is the second actuator I have purchased. The first had 12 inches of travel and this one has 8 inches. I bought both for my RV. The 12" TV raises and lowers the bed to access the storage space below, which was previously done by two people to lift and install the support bar. The 8" was purchased to raise and lower the TV. The TV was set so high it was uncomfortable to view. With a pair of drawer slides and this drive I can now lower it to a comfortable viewing height with the flick of a switch and then return it to the transport storage position.I used a DPDT rocker switch which works well as the actuator has internal limit switches to stop the cylinder in the fully extended and fully retracted position.Both cylinders came with mounting hardware and worked perfectly My wife thinks I'm a genius, a testament to her work, otherwise she'd have a different opinion!
