Abstract
Sign apparatus for directory or other applications and having removable sign inserts positionable at any location along a dimension of the sign. The sign inserts are held in place by a number of elongated rails located behind the inserts. Each rail contains an elongate track with a slotted opening facing the back side of the sign inserts. The tracks receive an end of an elastically-deformable fastener attached to the back of the sign insert. Each fastener expands within the track to prevent unimpeded removal of the insert, while permitting the insert to slide within the track for longitudinal positioning of the insert along the rails.
