Blichmann Engineering 14.5 GALLON FERMENATOR CASTERS This set of 3 casters will fit Blichmann 14.5 gallon conical fermenters (they do not fit other brands). These swivel casters make it easy to move your Fermenator around your brewery. The casters feature locks so you can lock your Fermentator in place to prevent unwanted movement. These fit all F2 and F3 Blichmann Fermenators with channel shaped stainless legs (they do not fit older Fermenators with L shaped legs). They add 3.25" to Fermentator height. Note: casters and leg extensions are now compatible with each other.
