This stainless lid fits the 30 Liter Grainfather as well as the 35 Liter Brewzilla and Digiboil, and features a built in silicone seal that seals tightly when the boiler clips are applied. This has a 47mm hole in the center for attaching a still. Use with a Condensor (items P34, C05, or C10 sold separately) to act as a condensing unit.
This does not fit the Brewer's Edge Mash & Boil or Anvil Foundry.
Or put a #10 stopper with airlock in the hole to convert your unit into a fermenter.
