The Signicade Deluxe A frame sign is the ultimate sidewalk advertising solution for those that need quick change graphics. The heavy-duty plastic sandwich board has two recessed 24×36 inch graphic areas on the front and back. 24″ x 36″ corrugated signs slide easily into place for display and these rigid sign inserts can be swapped out with new printed inserts without having to replace the entire frame. Our graphics are full-color UV direct printed coroplast for a long-lasting durable vinyl print.
