  • Publication number: 20150068144
    Abstract: A rebar cap assembly, for use in connection with a rebar rod with a free end includes a metal casing and a circular metal disc independent of the casing. The casing has a side wall with a cylindrical shape extending between an open end and a closed end with a top wall for receiving the free end of the rebar rod. A shoulder extends annularly about and radially from the side wall into the closed end. The side wall has an outer surface with a plurality of retaining tabs to secure the rebar cap to the rebar rod. The disc extends to a circular perimeter in a cantilevered fashion radially outwardly from the closed end of the casing. A bond is sandwiched between the top wall of the casing and the disc for securing to the disc to the casing.
