I have a white melamine closet storage system. I need some more components to do a reconfiguration. I have not been able to identify the particular system online or in the local stores. The side panels use a metal fastener system to attach to a back wall bracket. The fastener has screw adjustments to tighten to the bracket and do some vertical adjustment. I have attached a picture of the fastener and the wall bracket.
Any info would be appreciated.
