Actually the basic negative holder Nega 205 does not have beveled glasses, the sides are simply ground. The glasses are just placed there, not really blocked.
In the Lagraneg, Laraneg and Negateil the dynamics of clamping the glasses change and require bevelling.
Just to make clear. A sheet of AN glass has two sides, one with the AN treatment and the other side smooth.
The original Durst glass has a bevel only on the AN side as seen in the attached image. All 4 of my glasses are like that and are the original glass that came with the enlarger. I bought the enlarger from the first owner.
Having said that, Knight Optical indicated to me that their technician put a bevel on both sides (the smooth side and the AN side).

as long as it fits under the guides of your negative holder, it makes sense
This would be a good 'second choice' as the glass they sell is only 2mm thick, rather than 3mm used in the Durst. Per KHB, that is the thickness of glass in the Omega F 10x10 glass carrier and presumably the thin glass works fine in that setup.Originally Posted by Daniel Unkefer
However, the Durst CLS2000 blows air, quite forcibly, on the glass and I am concerned with the thinner glass flexing.
Fingers crossed...
I have cut and beveled AN negative carrier glass in the past, so if the new glass is not correct, I can rework it.
I have about 15 sheets of negative carrier glass in both AN and smooth counting all my carriers and spare glass.
Even fine-grit black silicon-carbide emery cloth, along with water, can relieve sharp edges sufficient enough for safe handling. Just don't scratch the faces. And I stipulate emery cloth due to its greater strength and skin protection, rather than wet-dry sanding paper.
They did not bevel it. I can send it back and have them re-do it, bevel it myself, or take it to the local glass shop that cut and beveled the edges of my 12mm contact printing glass.
Waiting to hear back from them.

BTW the glass is beautiful!! The AN surface appears to have the exact same texture as my Durst AN glass.
I thought my existing glass was fine, but by side-by-side comparison to the new glass, my existing glass looks all beat up.
This was the last print I made on the old glass on Ilford MG FB 11x14 inch.
