How do the Mag Flips work?

[Dez]

Anyone have one on 1/2" glass? I can't seem to find anywhere that has the large model in stock.

My glass is 1/2". Like I said earlier the large model should work great if you can find one. I bought mine from J&L, they only list one model and when I received it, it was the medium. Still works OK.
