Mo3231 PC-225 BAR SUPPORT FOR CONCRETE ABSTRACT OF THE DISCLOSURE The rod-support chair of the present invention comprises a plastic channel made of a thermoplastic resin preferably selected from the group consisting of polycarbonate, aromatic polyester carbonate and aromatic polyesters. The channel is further characterized in that its physical dimensions and material properties permit its elastic and bending across its long dimension around at least part of the circumferential cross- section of a reinforcing rod and provide support for the rod for a period which is necessary for the concrete to set. The channel in its "in use" configuration is left in the cured, or set concrete and does not interfere with the setting process nor does it contribute to rust formation.
