ABSTRACT:
A single unit, stiff and strong plastic molded wheel spacer for a reinforcement rod used in concrete is split into two sections connected by an integral hinge at one end and fastened together by a ratchet assembly at the other end. The rod is gripped at the center of the wheel by a pair of saddles, one on each section. A finger attached to one of the sections between the saddle and hinge prevents the rod from moving past the saddle to the hinge.
