Look, this is either a machine shop or rich guy tool as it is very specialized. BUT - if you need to lift a couple thousand pounds a couple mm/cm, this is the tool for you. Affordable, well welded, and fit for purpose to lift a mill 1/2" so you can put drill rods under it to move it to 36" over.Have not used it yet, but nonetheless it is a source of delight. Actually, not true - hoisted my car on a 4 post lift and lifted a corner effortlessly w this bar!
