Abstract: The present invention teaches a modular fixture (also sometimes in the trade referred to as fixture-ware) system, the features of which include and are characterized by the user's ability to set the system up and "knock it" down without the need of tools. This attractive and unique fixture system includes one or more lockable bracket assemblies which may be lockably positioned at any one or more of several locking positions, while at the same time facilitating locking at any of a substantially infinite number of positions. At least one vertical support member is formed with what may to some look like an I-type beam configuration. The differences between this configuration and an actual conventionally used I-beam, however, are apparent. The bracket assemblies include non-vertical portions adapted to support hanging articles, such as by way of example only, clothing, which may be on hangers.
