This stainless lid fits the 35 Liter Brewzilla, 35 Liter Grainfather, 35 Liter Robobrew, and 35 Liter 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. Fits all versions of the Robobrew, Digiboil, and Grainfather, but does not fit the Brewer's Edge Mash & Boil. This does not fit the Anvil Foundry.
Or put a #10 stopper with airlock in the hole to convert your Robobrew, Digiboil, or Grainfather into a fermenter (see the thumbnail above).
