An electric A-frame jack like the Stromberg Carlson # JET-5000 that you were looking at will be responsible for supporting and lifting a trailer's tongue weight. You will just need to make sure that the jack you choose has enough capacity to support your trailer's tongue weight, which is typically around 10 to 15 percent of its total weight. It's a good idea to choose a jack with a capacity that exceeds the tongue weight, as this just allows it to work under its limit which will lead to a longer lifespan.

This Stromberg Carlson Trailer Jack features a weight capacity of 5,000 pounds. It will provide you with 23 inches of total lift and its outer tube has a 2-3/16 inch diameter.

I have attached a short video demonstration on this jack that you can check out, along with a link that will take you directly to our available selection of electric A-frame trailer jacks.
