Reinforcement bars inserted into the first and second cradles are retained within the channels by retaining members protruding from the opposing sidewalls. A first base support member spans a central opening in the base between the first legs. Second legs extend upwardly from the first base support member and connect to the cradles. Third and fourth legs extend upwardly from opposing ends of the base and connect to the cradles. The structure includes fillets at various points on the cradles, including fillets connecting the cradles to the shoulders of the first legs.
