Of course! why didn't I invent this? just the job for filtering your brew as you fill your Barrel or other final container, a further enhancement might be a 2" version for Barrels with a 2" opening . . . . . There, I've just invented something, but please don't tell anyone, it might nullify my Patent/copyright application! If all goes well, I will be rolling these 2" versions out in a couple of weeks after a short trip to China and back!.
