Upgrade your FermZilla Conical or All Rounder with the new 2″ Tri-Clamp Lid from KegLand. Add yeast, hops or even take samples from a wine thief from the top and not have to remove the entire lid.

This particular lid was designed in order to suit a growing number of customers desire to dry hop without exposing the batch to oxygen from opening the lid. By using this lid in conjunction with the FermZilla 2″ Butterfly Valve and Hop Bong Kit, you will be able to purge CO2 into the tube and expel all the oxygen inside it and dump freely into the vessel.
