ABSTRACT:
The stackable jack stands have a base defining a central opening, a support bar centrally disposed above the base, and a plurality of legs connecting the open base to the support bar. The support bar has a length less than the length of the central opening in the base. In this manner one jack stand may be placed over another so that the jack stands nest together in order facilitate storage and transportation.
