Each band has a plurality of threaded studs that extend radially outward from the outside radial surface of each of the bands. The bands have a plurality of selected interchangeable risers, each of the interchangeable risers is configured to extend a desired distance from the outside radial surface of each of the band. The risers have a plurality of bore holes that are adapted to receive one of the threaded studs. The risers are detachably mounted to the bands by means of the threaded studs. The bands are fastened together around a carrier pipe to support the carrier pipe on the selected risers at a desired position when the carrier pipe is inserted into a casing pipe.
