Looking for Anti-Newton glass for a Beseler 6x9 negative carrier.

Knight Optical has a standard piece I could use in my Beseler 6x9 carrier, though it's a little thicker than I'd like (3mm vs. 2.2mm). They're in the UK and the cheapest shipping is essentially equal to the cost of the glass.

Does anyone know of current US suppliers?

Durst 4x5 AN glass shows up on ebay from time to time. I cut a broken 4x5" piece for my 6x7cm carrier.

Is this what you are looking for?

google helps, search AN glass & there several sources.

Thank you Patrick! The glass you linked to fits the #8072 6x9 glass carrier for the Beseler 23C, but I contacted KHB and Kevin says he can supply the (slightly different size) AN glass I need for a #8347 6x9 carrier for the Beseler 45 (a detail I didn't mention in my original post). He said the 8347 is rather rare so he doesn't list the glass for it on his website.

Just go zo the next Glazier or picture frame shop. They can crop you a piece of glas that is used for protecting pictures from UV light, in German called "Museum Glas". This have also an etched side like anti newton glas. Works well and quite cheap.
