Cornelius Keg Fermenter Lid via Austin Homebrew Supply. It has a 3/4″ Hole that’s designed to accommodate a #3 drilled stopper (included) and airlock (also included). That allows you use a Cornelius Keg as a fermenter. Use a 5 gallon keg as a secondary for a 5 gallon batch, use a 5 gallon keg as a primary fermenter for smaller batches or use a 10 gallon Cornelius Keg as a fermenter for 5 gallon+ batches
I have two 10 gallon kegs that I use as primaries. This allows you to do quite a few things including, easily transfer under pressure, ferment under pressure, carbonate in the primary fermenter and carbonate and serve from the primary (with a cut off dip tube).
