Aquarium Masters Tempered?

[SUS]

I purchased a 60 gallon rimless frag tank from aquarium masters. I’d like to drill it but I’m worried it may be tempered? Their site doesn’t have specifics but say “most models are made with tempered glass panels”
I’d just assume the frag series is not tempered as most people would be drilling a frag tank. They are closed for the weekend so thought I’d ask here before drilling...

Thanks!

Ended up drilling side panel. Not tempered. In case anyone is ever interested

Thanks, that's a useful data point.
