A concrete reinforcing bar support including a base, a support structure extending upwardly from the base, a first clamping member affixed to the support structure and extending upwardly above a top surface of the support structure, a second clamping member affixed to the support structure and extending upwardly above a top surface of the support structure, and a third clamping member affixed to the support structure and extending upwardly above the top surface of the support structure. The second clamping member has an interior surface generally facing the interior surfaces of the first and third clamping members. The first clamping member is separated by a space from the third clamping member. Ribs extend inwardly from the interior surfaces of each of the clamping members so as to compressively contact a reinforcing bar placed interior of the clamping members. The support structure has a generally H-shaped cross-section in a plane parallel to said base.
