For you guys wanting multiple racks this is easy-peasy....
Use big stainless eye-bolts at the lowest rack position...see 'em down there?
Then use 8 inch stainless bolts and fender washers and nuts to make legs on the cooking grates, like this....
Then depending on the height of your DrumPit, you can have as many levels
of cooking racks you want....easy access for pulling racks as you cook...
I can fit 6 racks in mine comfortably...but I usually just use 3-4 at a time...
