Abstract: A pot holding arm is removably secured to a semicircular receiving member in one of a plurality of retaining pockets and cooperating positioning slots. In one embodiment a semicircular casting has a plurality of pockets and a slot in association with each pocket. These slots are adapted to receive and retain a pot holding arm. This semicircular member may be secured to a wall or to another similar portion to form a circular member. In one embodiment it may be clamped to a pipe and in another embodiment may be slightly larger so that it may be rotated on the pipe or post. This rotating circular member is longitudinally retained on the pipe by an attached collar. In another embodiment the semicircular cast member has extending T-forms but without a retaining bottom portion. A pot holding arm as used with each of these extending T-forms has a limit stop so that this arm does not slide below a determined point on the receiving and retaining member.
