This N Scale 1:160 piece includes four Pacific Northwest style headache racks, used on logging trucks. The piece has a framework around it to help prevent damage in shipping. I STRONGLY suggest it be ordered in the Extreme Detail material in order to retain the most detail with the least prep work. I have made these tall, and can easily be shortened by removing the bottom plate should you so choose.
