A hinge for rotatably mounting a barrier member to a structural member. The hinge comprises a first hinge assembly which comprises a first hinge bracket attachable to the structural member, a second hinge bracket attachable to the barrier member, a first hinge member mounted for rotation with the second hinge mounting bracket and a second hinge member mounted for rotation with the first hinge member. Both hinge members have correspondingly configured engaging surfaces which permit staged rotation between the hinge members. This facilitates a staged rotation of the barrier member in predetermined sequential increments as determined by the engaging surfaces. This first hinge assembly connects a lower portion of the barrier member to the structural member and is responsible for bearing substantially all of the weight of the barrier member. The invention further comprises at least a second hinge assembly for providing rotational alignment between an upper portion of the barrier member and the structural member.
