ABSTRACT:
A stationary jack stand for supporting such things as the draw bar end of a trailer has a base, four struts and a cap, capable of ready assembly and disassembly. On the base are four recesses into which are inserted the lower ends of the respective struts. The cap has four pockets much closer together than those of the base into which upper ends of the respective struts are slid. When a weight is applied to the top of the cap all parts remain interlocked together. To disassemble, the top is lifted free from the struts and they in turn can be lifted free of the recesses in the base.
