Abstract: A free standing portable and knockdown tennis net support system, made up essentially of tubular light metal components, readily assembled for use on any suitable playing surface, and quickly disassembled for compact packaging for transportation. The components of the system having a weight, configuration and relative disposition whereby in use, the normal tensioning of the tennis net acts to flex a base portion of the system towards the playing surface. The system is made up of a pair of spaced apart net anchor elements; each of the anchor elements being attached to opposite ends of an elongated, flexible stretcher base member. Each anchor element is provided with attachment members for supporting a tennis net in a substantially vertical plane, rather then away from such playing surface.
