ABSTRACT:
The sign post coupler is a breakaway coupler for use with highway signs having a sign post and a ground post. The coupler is a hollow, tubular, integral coupler made from ductile iron and having a sign post socket, a ground post socket, and a shear section joining the two sockets. The sign post socket has a bottom wall and at least one side wall extending vertically for 360.degree. around the bottom wall, the socket defining a cavity for receiving and supporting one end of the sign post. The ground post socket has a top wall and at least one side wall depending vertically for 360.degree. around the bottom wall, the socket defining a cavity for receiving and being supported by one end of the ground post. The sockets taper inwardly towards the center of the coupler to define a shear section having an annular groove of reduced thickness defined therein. The shear section breaks upon impact of a vehicle with the sign post to separate the post sections.
