Advanced Tool Design Model ATD-7449 22 Ton Jack Stands

Do not buy this product, I figure it was a good idea because the pin style could not possibly fail. However, care was not taken when constructing this product. The bottom plate is about 1/4" steel and the welds sure penetrated well, but the welding overheated so much the bottom warped and both jackstands are not flat. The corners do not touch the floor just imagine how little of the bottom is actually making contact with the concrete, mostly only in the center, not my idea of safety. I checked with some other people with similar style jackstand made back in the good old days possibly in the USA too, and theirs is flat. In my opinion if the manufacturer cannot avoid warping then the bottom should have been machined flat and using a thicker material to begin with.

These jack stands work very well..The design makes for more room under the vehicle..The upper shoe that you place to the under side of the vehicle is much better suited for finding a good contact point under the vehicle..Amazon gave me free shipping and super fast shipping..I hope I never have to use the old ratchet type, long shoe jack stands again..Saftey is what these stands are all about for me..
