ABSTRACT OF THE DISCLOSURE A concrete reinforcing rod chair comprises a frusto-conical tubular body or hollow tapered body with open ends to permit mutual stacking, the body having two pairs of diametrically opposed troughs in one or both ends thereof, with each pair having a different depth. The troughs are arranged on the body so that a continuous strip of body member material extends in the longitudinal direction, either from end to end between adjacent troughs or from the bottom of each trough to the opposite end of the body. The continuous strips of material provide strength against axially directed compressive forces. In addition, a continuous strip of material is provided in the circumferential direction intermediate the two ends, to provide additional strength.
