Abstract: A fence assembly characterized by fence posts defined by adhesively assembled halved molded plastic resin portions slidable and rotatable on a rod embedded in a concrete mass at a desired location. Each of the fence posts includes one or more pockets which are adapted to receive a generally ball shaped socket disposed at each end of a crossrail. The preceding arrangement not only permits crossrail assembly at fixed fence post locations but, as well, allows for inclined positioning of the crossrails to satisfy ground contour conditions and the lateral positioning of the crossrails in the instance where sections of installed fence are angled with respect to each other. The invention obviates the need for nails, supports or the like, achieving expeditious and less costly installation, together with minimized maintenance.
