Abstract: A spacer that connects to a reinforcement wire mesh at an intersection of a first wire and a second wire includes a first triangular body portion and a second triangular body portion, wherein the second triangular body portion is orthogonal to and bisects the first triangular body portion. The first triangular body portion includes a first apex, a first base, and a notch on each side of the first triangular body portion proximate each end of the first base, each notch allowing a respective end of the first base to flex toward the first apex. The second triangular body portion includes a second apex, a second base, and a clip extending from each end of the second base, each clip configured to surround the second wire.
