ABSTRACT:
A knock-down support stand or trestle for use as a sawhorse on construction sites and for home use constructed of pre-cut or pre-formed components that are readily assembled together in interlocking engagement without need for use of fasteners of any kind. As the load on the support stand increases, the components of the support stand become more securely interlocked together.
