The bottom rail further includes an opposing pair of curved ends each having a projection that is received in a notch in one of the vertical rails. The connection is then welded. A foot is pivotally attached to each of the vertical rails. Hooks are attached to one of the vertical rails for attachment of a second rail barricade.
