0072 Animated Sign - 0072 Sm. Railway Express Size: 2.1" wide x 2.25" tall

Miller Engineering's Billboards are easy to mount on your structure. Simply cut a small .75" wide slot in the roof of your building, insert the sign. Use a small amount of hot melt glue or 5 minute epoxy on the topside of the roof, at each end of the sign, plug in the connector and you're done. It's that simple.
