Link for foldable portable roadway warning device
A portable roadway warning device comprises one or more rumble strips. Each rumble strip comprises at least two modular strip sections, each made of a polymeric material having top and bottom surfaces and end edges and side edges. At least one of the end edges of each of the strip sections has a plurality of aligned alternating notches and tabs, and connecting links hingedly connecting the tabs at one of the end edges of one of the strip sections to respective aligned tabs at one of the end edges of another of the strip sections. Each connecting link includes a Ushape link plate bracket and a pair of frangible rods that are configured to break at less than the tear strength of the polymeric modular strip sections.
