ABSTRACT:
A display apparatus comprising a U-shaped member having a bore extending through a bight portion along an axis perpendicular thereto where the bore is characterized by having a polysided cross section adapted to coact with a polysided plug having preselected dimensions so that the plug may fit within the bore. The bore and the plug have tapered complementary sides so that a snug fit is provided. The number of sides may be infinite so as to produce a bore having a circular cross section.
