ABSTRACT:
A welded wire concrete reinforcement spacer having spaced uprights with tops projecting up from the bottoms toward one another, a support means on the uprights and located below the tops of the uprights, the tops being spaced sufficiently to allow a reinforcement member to pass therebetween but spaced sufficiently close together as to prevent easy and accidental withdrawal of the reinforcement member from between the uprights.
The spacer can include a second support means for supporting a second reinforcement member, and the first support means can include a cross piece secured to and extending between the uprights, or a notch in the tops of the uprights. A concrete reinforcement spacer and reinforcement assembly is also included, as well as a method of use for the same.
