Another small design change that might go unappreciated until explained. One reason to rotate the handles was it reduces the width needed for a 3-vessel single tier system by nearly 12”. With side mounted handles the kettles need additional spacing, so the handles do not touch. You also need additional room if you plan to hang the lid on the handles when not in use (wait you didn’t know the kettle has a built-in lid holder!?). Instead the lid now hangs off the back and out of the way while saving you 12” of space in your brewery. Another benefit is when carrying the kettle around you won’t be banging your knees against the welded couplers.
