baker’s rack [bey-kers rak] noun
Also called a speed rack. Vertical metal racks, often on wheels, designed to hold full-size sheet pans so that the pans are slightly separated from one another.
Baker’s racks are found in almost every professional kitchen, be it a bakery or regular commercial kitchen. They can hold hot trays coming out of the oven or store chilled items in a walk-in refrigerator. The racks can also be built into delivery trucks and pantries and can be stationary or mobile on wheels. These are a truly multi-purpose piece of kitchen equipment.
