Jack is sturdy and works great. I welded it on to a 16' lowboy. I did notice some minor rust on the foot after a week or so. I'll just spray some cold gal on it and it'll be fine.
Solid jack. I installed it before I flipped over my trailer to work on it. The 6\" I beam bent where the jack was welded during the flip but the jack wasn't damaged at all. I'm very happy with it.
