Abstract: A merchandise display system for mounting on and to virtually any merchandise display frame, and in particular an existing gondola, having at least two horizontally spaced-apart mounting stanchions each having a plurality of apertures defined therein. The display system includes a universal mount with two universal brackets that are carried by a crossbar and that are selectively movable on and along the crossbar for alignment with the stanchion apertures. Once the universal brackets are so adjusted, the universal mount may be secured to the existing display frame by engaging the universal brackets with the aligned apertures. A frame assembly including a PEGBOARD.RTM. is then removably secured to the universal mount to complete the inventive merchandise display system. The configuration of the PEGBOARD.RTM. i.e., the size, spacing, and pattern of the holes in the PEGBOARD.RTM., may be varied as desired to accommodate different merchandise display configurations.
