ABSTRACT:
A novel adjustable holder and support device for books, files, recorded music discs and the like comprised of two upright end units each with a longitudinal leg that extends under the materials being contained. In addition, an optional flat extender may be positioned between the two end units singly or in plurality. Said units in combination, hold the contained materials on an even plane above the surface upon which the holder rests, one unit leg having a female opening to receive the second unit's male-tongue leg. The two base legs interlock, when positioned, by means of a plurality of indexed shapes along the outside edge of the male unit tongue and the facing edges of the female unit's opening. This engagement thus allows for easy adjustability while insuring that the space allotted for containment is fixed against change while in use.
