Please also read description for CE970 as this is a two part kit. Holds 12 bottles upside down at one time. Load bottles out of the cardboard boxes they come in and into these plastic racks. These racks then sit down on a base used to either rinse or gas flush the bottles, depending on what you have hooked up to the base (water or inert gas.) You will defintely want more racks than bases. L 15.25" x W 11" x H 4 5/8" Swing top bottles will fit if wire swing top is removed.
