This stainless lid features a built in silicone seal, and seals tightly to the Mash & Boil lid clips. This has a 47mm hole in the center for attaching a still. Use with a Condensor to act as a condensing unit. 12.5" overall width.
Or put a #10 stopper with airlock in the hole to convert your Mash & Boil with lid clips into a fermenter (see the thumbnail above).
This also fits Anvil Foundry units. This does not fit the Grainfather or Robobrew.
