Abstract: A label holder for displaying information-containing non-adhesive labels or signs on a channel member at the front of a variety of forms of merchandise shelves in a supermarket or the like, particularly adapted for secure support and ready attachment to both Streator and Lozier type shelf systems wherein the height and configuration of the channel members are different. The label holder may be a co-extrusion of an opaque body panel and a transparent cover resiliently connected along their lower edges to define a label-receiving pocket therebetween. An upwardly and rearwardly extending leg member is integral with the rear of the body panel and underlies and extends behind the channel member. A lower finger is also carried by the rear of the body panel and is biasingly engaged with the upper surface of the lower flange of the channel member. An upper finger is provided on the upper edge of the body panel and is biasingly engaged with the lower surface of the upper flange of the channel member.
