Difference between 6025.500 and 6025.501 magnet extension

[KStatefan]

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.

6025.501 is half of a 6025.500, this is used to up the magnet strength of an existing magnet holder, you keep the existing inside set. The only way to get to 19mm though is the full 6025.500 and for this application, it is what I would do, the existing 6025.515 with swapping only the outside will just hold on 15mm, and it would be much more secure with the full pair.
