Topic: Garlando top glass: thickness?

[Maxgarlando]

Hi,

I’m trying to get a new top glass cover made (not the playing field) for my older model Garlando coperto. I know it should be tempered glass.
What thickness should I get? I’ve heard 4mm (0.157 inch) somewhere but the recess is bigger, about 7mm.
Can someone confirm what the original is?

Kind Regards, Max
