Making sure that your plates will fit
By slightly increasing the thickness of our cassettes, we ensured that even 2 mm glass fits perfectly, just like a glove. Back in the day, thinner 1–1.5 mm glass was commonly used, making some older cassettes incompatible with the 2 mm glass that is standard today. And because we still use back springs like the originals, you can also shoot with thinner glass or even tin plates.
