If it has an Orange built by Date and Initials label and says Tempered glass on that label--its all tempered. Don't drill it.
If the tank is not Tempered (white label) then the label is often times up "under" the top rim. If the tank is all tempered its up under the top rim, orange and says tempered glass with the date and initials.
Again, I don't know if this is industry standard, but I am starting to see a method to the madness.....
These stickers are on the tank we drilled......DC
