I was calculating with a safety at 3.8 which put me at .93", I was rounding up to 1" to be safe. With a safety of 2.5 I'm at .75". Problem is, I can't FIND 1" anywhere. I've called 15 suppliers and manufacturers in the area and the best I can find is .75". I'm still waiting on hearing back from a couple but I'm not getting my hopes up. So, looking at .75" will that really be enough? Bear in mind there will be 1" perimeter on all sides of the glass holding it in place, so really only 34" high of exposed glass.
