Abstract: A display panel assembly comprises a display panel, a base for supporting the display panel, and a pair of spaced panel supports coupled with the base, each panel support having a slot. An adapter for the display panel assembly comprises a panel support portion comprising a channelway defined by a pair of spaced flanges and an interconnecting web, and an insert portion comprising an insert flange extending from the web and terminating in a spacer extending generally parallel to the web. The spacer is adapted for receipt in a panel support slot and the channelway is adapted for receipt of an edge of a panel therein, the channelway having a width different than the width of the slot. Panels having a first thickness can be supported by the panel support slots and panels having a second thickness can be supported by the adapter inserted into the panel support slots.
