The Hatco GRSBF-72-I 73 1/2" Countertop Warming Shelf is a workhorse for commercial kitchens, delivering fast, consistent heat with five independent warming zones. Part of the Glo-Ray® series, this built-in unit is engineered for durability with a hard-coated aluminum top that resists corrosion and streamlines cleaning. Its thermostatic controls—paired with an illuminated power switch—ensure precise temperature management (up to 200°F), while included mounting brackets expedite installation. Ideal for high-volume restaurants, this shelf maximizes counter space (21" deep) and accommodates countertops up to 1 1/4" thick, making it a versatile solution for holding soups, sauces, and ready-to-serve dishes. The fiberglass insulation preserves heat efficiency, reducing energy costs while maintaining food safety standards—a critical feature for operational success.
