The Glo-Ray® Heated Shelf is a free-standing shelf that is 24" wide and 9-3/4" deep. It features an adjustable thermostat, an aluminum base, and a stainless steel top. It is cUL, UL, UL EPH Classified, and ANSI/NSF 4 certified. This heated shelf has a blanket-type element that provides uniform heat distribution. It also has fiberglass insulation to keep the heat at the holding surface. The built-in adjustable thermostat allows you to control the surface temperature. The shelf comes with a 72" cord and plug attached. The Glo-Ray® Blanket Heating Elements are warranted against burnout for one year. The shelf has an extruded aluminum base with non-slip rubber feet and a stainless steel top. It is available in widths ranging from 18" to 72" and depths ranging from 6" to 25.5". The standard legs for units 36" or wider are 4" legs, while units 30" wide and under have 1" legs. There are several options available at the time of purchase, including different designer colors for the top surface (clear anodized, black, navy blue, warm red, gray granite, white granite, hunter green, and antique copper). There is also an option for a hardcoated surface instead of stainless steel on certain models. Accessories for the heated shelf include a slant leg kit for models 12" deep or deeper, 4" adjustable legs (standard on GRS-36 units and larger), and a pan rail for 19.5" models only. The pan rail is available in 2-pan, 3-pan, 4-pan, and 5-pan configurations.
