Universal Seal Cage Lantern Ring (USCLR) is a new design in seal cage/lantern rings.� It allows the user to custom fit his seal cages or lantern rings on the job, rather than stocking given diameters for each shaft size.� It comes in roll form as does bulk packing and is made of special high temperature-wear resistant materials.� No more need to waste time searching for the right diameter seal cage/lantern ring or having it custom made.
