ABSTRACT:
The spacer support (20) includes a support base (22) and a receptacle (26) which are welded together at interfitting annular flanges (46 and 64). A bearing plug (24) includes a circular support plate (48) covering the upper surfaces of the radial walls (36), with a tapered stem (50) projecting into a tapered center opening (34) of the support base (22). The flexible engagement fingers (66) allow one way movement of the rebar rod (14) into the receptacle (26), and the protrusions (18) of the rod engage the ends of the fingers (66), prohibiting separation of the spacer support (20) frown the rod (14).
