Clear Plastic Bins disengage from plastic backplates to allow straight-entry … the ability to mount a Pegboard or Slatwall fixture without the clearance-requiring-need to tilt up. These Bins can therefore be mounted in tighter arrangements and close under shelves and each other. The backplate design is a shallow-trough microcosm of  Slatwall itself (SEE “Slatwall Cutaway: No Metal Insert” for how retail Slatwall engages fixtures.)
