ABSTRACT:
A corner member for a front-loading poster or picture frame is disclosed. The corner members are assembled between adjacent frame sections which have rotating cover members hingedly attached to base members. One or more raised protrusions or ridges are provided on the surfaces of the corner members adjacent the frame sections in order to provide improved manufacturing, assembly and operation of the frame. The raised ridges keep the cover members centered between the corner members and eliminate binding during opening and closing of the frame sections.
