Abstract: A modular display system has a support base and a vertical post mounted on the support base. The post is formed with threaded bores. A plurality of bars, including short spacer bars for hanging display bins and hang bars for hanging clothes hangers, for example, are screwed into the post and they project radially from the post. Each of the bars has two threaded stems, one to screwed into the post, and the other one to be covered by a threaded puck. The display bins have corresponding bores aligned with the bores in the post and adapted to receive the threaded stems of the short spacer bars to reach through and for the puck to bolt the display bins to the spacer bars.
