ABSTRACT:
A resilient support member for reinforcing steel having first and second legs separated by an open cavity and being normally axially aligned in the inoperative position of the support member. The support member is adapted to assume an operative position by deforming the legs inwardly toward each other around a reinforcing steel bar such that one of said legs is perpendicular to the other and with the reinforcing bar being disposed within the cavity which, in the operative position, is substantially closed around the bar. The support member may be secured in this operative position with the outer ends of the legs abutting the inner surface of the walls of a concrete form.
