Abstract: A support is provided for reinforcing rods or mesh. The support includes a plate of substantially planar construction. A cruciform structure is provided beneath and supporting the plate. The cruciform structure includes a plurality of legs and tips depending from the legs. The tips are adapted to expose a relatively minimal part of the support with the support being embedded in a substance such as concrete. On top of the plate is provided a structure to limit movement of the rod or mesh transversely of the plate. Specifically pairs of pins toed in towards one another are employed or fins are employed with ramps thereon to restrain the movement of rods or mesh which are supported on the plate.
