What is the difference between these two magnets? The catalog and the manual list a 6025.500 for up to 20mm glass. I saw a 6025.501 online that said it was good to 3/4" glass. Trying to get my 6095 nanostreams to work on the back glass of my IM 100EXT. I forgot about the acrylic panel infront of the 15mm glass.
