85 gal. UDS.Great minds deteriorate with great rapidity!
My warehouse is 8 blocks from a Grainger and I was looking at the exact same page of their catalog thinking the same thing. Normally there is no shipping if you pick it up at the store. I am also studying up on the grate issue. I have welding equipment and some expanded metal on hand, so am considering the custom fab route. However, making pretty circles without jigs is a pain. If I find a good solution I will share.
