ABSTRACT:
A slab bolster upper for supporting rebar in a reinforced concrete structure while the concrete is poured and thereafter cures, is of molded plastic construction and is formed with horizontal and vertical voids that facilitate concrete placement and break up potential shear planes. Opposite ends of each unit are provided with complementary buckles to interconnect with like units to form a continuous support of desired length.
