Abstract: A signage system comprising a prism-shaped tri-panel louver having a slot at each corner into which can be slid a clip. The clip is generally V-shaped with a pair of opposing sides joined at one end to form an apex. At the apex end is a pair of opposing fingers which are generally parallel to the clip sides. The fingers form a slot on each side. The clip is slid and retained by a friction fit within the slot such that when three clips are installed the fingers and slots formed therein can hold the sign graphics strip. The clip can flex somewhat to allow for insertion in a slot in the louver.
