The Blichamnn TopTier Utility Shelf is an excellent size for the Tower of Power Control Module, a counterflow chiller, or smaller items like a refractometer, timer, gloves, or your next hop additions. Mounts directly to the stand, keeping everything you need right where the action is. The TopTier Utility Shelf is 10in. x 10in. and has a 50lb capacity, therefore, should not be used for kettles or coolers.
