The Vevor floor jacks are adjustable steel jack posts designed to provide temporary or extra support for beams, patios, and construction areas. Built from Q235 carbon steel, each jack supports up to 18,000 lbs for heavy-duty lifting and stabilization. The adjustable height range of 19-36 inches offers flexible positioning for different support needs. Height adjustment is simple with a rotating lever, and the integrated welded base plate helps provide stable installation. This 2-pack is suited for leveling and temporary structural support applications.
