A spacer for welded-wire concrete reinforcement includes an upper pigtail portion, a central shank portion, and a lower hook portion. The lower section of the shank portion slopes outwardly and downwardly to define a noselike spacing projection to position the wire reinforcement relative to the surface of the concrete mold. The spacing nose also serves as a handgrip for facilitating installation of the spacer on the wire reinforcement. The spacer requires only one pair of intersecting wires for installation and is adapted for use with all mesh spacings, including helical cages, and all wire sizes. |
