Hard to tell what you mean by "05 mm".
I measured my ring to be about .01" thick at its thinnest inner diameter, the part which rides on the disk. That's about a quarter of a millimeter. In addition most LPs have a somewhat thicker part outside of the grooves at the beginning, which all cartridges have to deal with.
If I had a cartridge that rode so low that it couldn't deal with this ring I would think there's something wrong with the cartridge. In fact, many years ago I was delivered a Shelter cartridge from Japan that rode very low. I sent it back and received a replacement that rode at a correct height.
In any event you can inquire about the ring's thickness with Wayne Audio, or see if he offers a return option.
