Our Jersey Barricades come in a set of 5 concrete colored barricades per package. The prototype models are based upon official DOT blueprints. Barricades are employed in a variety of uses including but not limited to: Railroad intermodal yards, highway lane separators (Especially in New Jersey! but also throughout the USA), truck stops, around community administration buildings, construction sites, and storage yards. The barricades measure 2 1/2" long. These barricades are used and abused, representing barricades that have been around for awhile - showing wear and tear in the way of cracks, gaps and chunks missing. We also offer them as factory new condition.
