Abstract: A trunk organizer is disclosed having a holding bar assembly, a plurality of receptacles and a mechanism for attaching the receptacles to the holding bar assembly. The holding bar assembly preferably comprises three axially aligned bars which longitudinally and axially slide toward and away from each other. Two of the bars can be axially moved away from each other for adjusting the length of the holding bar assembly. A compression spring between two of the portions allows for one portion to be held in a biased position relative to the other.
