The San Jamar 4 qt The Dome® Garnish Center (BD4005S) is an NSF-certified, all-in-one garnish and condiment center that is designed to maximize the efficiency of any bar by placing necessary garnishes within arm’s reach. This garnish center fits on a standard mixing rail, and it comes with two snap caddies so your bartenders can store straws, stirrers, and picks. The San Jamar - BD4005S - 4 Qt The Dome® Garnish Center can hold up to four quarts of garnishes, with one tray that is two quarts deep and four trays that are each one pint deep.
The center matching that description is the San Jamar - BD4003 - The Dome 6 qt Garnish Center.

Thanks for your question. Regarding this San Jamar BD4005S 4 Qt Capacity Garnish Center, the (1) 2 qt deep insert reaches to the bottom of the tray, and there is no room for additional ice. That said, the (4) 1 pint inserts are much smaller, and they allow room for either an ice pack (sold by San Jamar) or loose ice.
