Can someone out there who owns a Fermzilla tell me the exact inside dimension of the top opening? I have a Speidel fermenter and its top opening has an inside diameter of 4 7/8". I was curious if the tri-clamp pressure lid that is designed for the fermzilla would also fit the Speidel opening. I don't want it for pressure fermenting but rather just like all the extra ports it provides. I would still use the Speidel's locking ring so there is no issue with the threads matching as long as the lid fits snugly into the opening.
