Our patented wheel chair design has been copied but never matched! We offer the only wheels chair that locks in place and accommodates multiple sized bar. Be confident knowing that your rebar will stay where you place it. Use our 1'', 1½", 2'' and 3'' cover chairs for all concrete work including precast, utility vaults, slabs, barriers, foundation work and bridges. Use one of our Polylok ratchet style chairs instead of three of the competitors.
