An angularly orientable post includes a base and a rigid support extending substantially vertically from the base. The support has a first end secured to the base and a second end. A positioning member is supported by the support and positioned in proximity to the second end of the support. The positioning member is laterally movable relative to the support. A tubular shell is provided which is adapted to telescopically overlie the support and positioning member. The angular orientation of the tubular shell relative to the base is determined by the lateral positioning of the positioning member. The positioning member is locked in a selected lateral position which provides the desired angular orientation.
