This display unit comes with lockable acrylic hasp closures, air holes in the back of the unit and rubber "feet" on the bottom so it doesn't slide.  All displays come with flame polished edges.  The display unit is approximately 4 inches high, 8 inches deep and 22 inches long.  This unit is available in your choice of either all clear acrylic or our best selling, black acrylic.  The black acrylic displays all have black backs, bottoms and dividers. The tops (doors) and fronts are still clear.  The picture shows our older style (which is discontinued) 3 section clear display unit without black dividers/ends.  We will have a new picture soon.
