ABSTRACT:
A cage spacer for spacing reinforcing rods or welded fabric a specified distance from mold walls for poring concrete during construction projects. The cage spacer comprises two intersection bodies oriented perpendicular to each other and preferable with one body having a base higher than the other. A pair of pads on opposite ends of a first body base for stabilizing the body on the rebar. A pair of rebar engaging clips on opposite ends of the second body base for snapping onto and gripping a perpendicularly intersecting rebar such that the rebar is held securely in the clips. The cage spacer attaches over the intersection of a pair of rebars. At least one apex of the bodies engages a mold wall to keep the mold wall a specified distance from the rebars while concrete is being poured in the mold.
