does the job. 5 stars if it didn't have such a unnecessarily long winded thread, although most of them do. a coarser thread would shorten the cranking time.
I up in years and have trouble cranking undersized trailer jacks and finding blocks when needed. This jack may be a little oversized but it is easy to crank even with a heavy load. First time I’ve used an adjustable leg and I really like it.
20 foot car hauler trailer 6 x 12 enclosed trailer. This Jack with the side crank is less trouble prone in the long run doesn’t get rusty internally. As easy. the pin you can pull to adjust the height is very handy also.
