A rare Shelf Talker for angled, flat face shelving, though the adhesive back label strip also shown is easily obtainable from major manufacturers. The fixture mounts via pushpin to the shelf edge perforations. Judging by the loose tolerances of talker folds, this item appears to be heat bent as opposed to extruded.
There are many choices to allow a made-for-your-needs fit of label strip to your shelf. Talkers are available in even more configurations. But why not just consider a Label Strip with Built-in Sign Grip that allows instant use of Bib and Promo Tags throughout the store?
