ABSTRACT:
A support unit, e.g. a setter, is designed for convenience of stacking both in use and in the stored condition. Each unit (10, 20, 20A) is of circular plan outline and has a rim (13) having alternate upwardly-and downwardly-disposed castellations (14 and 15 respectively) whereby a pair of units (20, 20A) can be stacked closely together with their upper castellations (24, 24A) contiguous and their lower castellations (25, 25A) contiguous or can be stacked in the `use` position with the lower castellations (25A) of an upper unit (20A) resting on the upper castellations (24) of a lower unit (20).
