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.
