The Glo-Ray® Built-In Heated Shelf with Flush Top is a versatile and efficient addition to your serving surface. With a surface area of 31-1/2" x 25-1/2", this shelf features a hardcoat aluminum top for durability and uniform heat distribution. The blanket-type element ensures that your food stays warm for longer periods of time. The built-in adjustable thermostat allows you to control the surface temperature to meet your specific needs. This heated shelf also comes with a 36" flexible conduit that channels power lines from the shelf to a control box. The standard controller includes a control thermostat, an illuminated power switch, and mounting brackets for easy installation. The .75" flanged edge allows the shelf to fit into a countertop opening. The Built-In Heated Shelf is recommended for use in metallic counters, but can also be used on other surfaces as long as they can withstand temperatures up to 200°F. This shelf is available in various widths and depths to suit your specific requirements. Please note that models with a flush mount recessed electronic control box are not CE approved. Non-standard colors are non-returnable. Hatco is not responsible for any counter damage caused by heat from the warmer. Optional features include designer colors for the flush mount control bezel box, conduit in lieu of the standard 3' length, stainless steel top surface, and flush mount electronic or thermostatic control boxes with lighted power switches and cords.
