This BetterBottle Snap-On Blue Handle fits the necks of all sizes of BetterBottle carboys. It has a comfortable grip and is made of durable, reinforced plastic. Carboys will not tip when they are lifted with this handle, so their contents will not be disturbed. This handle will fit over carboys with closures, but will not fit over airlocks or other accessories.
Note: Blue Handles are designed for carrying BetterBottle carboys in suitcase fashion. They are not designed for lifting carboys at an angle in order to place them on shelves or to pour from them, because the handles may disengage.
