ABSTRACT:
A frame is comprised of a plurality of channel-shaped members each having an inwardly extending flange for supporting a display panel. A L-shaped member is inserted in each channel with one leg thereof extending inwardly in parallel spaced relation to the flange for gripping a display panel therebetween. The other leg of the L-shaped member and one wall of the channel are provided with corregations and a plug is inserted into the channel to dispose the corregation in interfitting relation thereby securing the L-shaped member to the channel-shaped member. The plug is provided with a hole and a wedge is forced into the hole to expand the plug into tight frictional engagement with the channel and the L-shaped member.
