Abstract
A bar spacer for concrete reinforcing bars. The spacer comprises, a foot portion to contact a form for concrete. A bar gripping portion is adapted to grip reinforcing bar for concrete. A plurality of spaced teeth are formed on the internal surface of the bar gripping portion. The teeth are arranged so that each tooth is out of alignment with the tooth next to it whereby each tooth can bend to a position past its neighboring tooth. This ensures that each spacer can grip and locate bars of varying diameter.
