Al,
I went out and looked at my jack and it is 4 1/4 inches high instead of two. It just says E-Z lift sissor jack on the box it came in and has a 3,300 pound lift capacity. It isn't a billit jack and has a baked on enamel finish. I got it at Sears and I did have to dig out a little gravel one time and set it in the hole to get it under the frame. It has a lift of 14 1/4 inches and has a reduction gear that makes it easy to use.
