Eliminate the physical exertion commonly associated with lifting and lowering a trailer when you use a Stromberg Carlson 3500 lb. Electric Tongue Jack. It does the heavy lifting for you, and has lots of other features as well. For example, the trailer tongue electric jack has equalizing bars that are easy to set, so you get better results, and two separate LED night lights that provide both added safety and additional illumination. The leg extends up to 23" and although it is heavy and durable, it's also surprisingly lightweight and easy to store.
