1/2 inch yikes that was definatly a 5 man job for a 4x8 box. 11/32 well within my spending limits thanks a ton man.
Especially when you consider its TWO layers of 1/2" all the way around!
I actually carry them with the lids off, and re-install the lids once the box is in place. Doing it this way can make it a one man, three woman job…
