Abstract
A device is provided for mounting shelf labels on supermarket shelving with a C-channel.

A metal clip fits into the slot to form a second return opposite the first return. A rail with a bracket and slide engage the first and second returns for mounting shelf labels. Plastic shelf rails for mounting wireless electronic shelf labels are also provided. The lower groove of the rail is shaped to engage latches at the bottom of the electronic shelf label which can only be removed by using a special tool. Also provided is a shelf rail made by co-extruding flexible and rigid polyvinyl chloride (PVC) materials. The plastic shelf rails have a notch on the back to accommodate metal shelf brackets. To prevent the electronic shelf labels from sliding, they are held firmly in place by a gripping pad. Shelf rails optimized for lower shelves tilt the electronic price display upwards. Two transparent plastic covers for the shelf rail and a plastic shelf rail with integrated cover are co-extruded with resilient ridges for holding…
