The Heated Black Glass Shelf is a built-in shelf with a length of 60 inches. It features a ceramic glass surface that provides uniform heat across the entire shelf. The thermostatic control allows for temperature adjustment between 100°F and 200°F, and it has a lighted on/off rocker switch for easy operation. The shelf is cULus and UL EPH Classified, meeting safety and sanitation standards. It is made of approved foodsafe material, making it suitable for placing food directly on the surface. The shelf is ideal for use on pass-through areas, buffet lines, and as hors d'oeuvre displays. It comes with a choice of frame finish, with stainless steel being the standard option. Optional features include a portable model with a cord and plug, an angled food stop to keep products on the heat zone, and different lengths ranging from 24 inches to 72 inches. The built-in models include a control box with conduit and cord and plug. It is recommended to use the built-in models on metallic counters, and for other surfaces, it is important to verify their suitability for high temperatures. The shelf can reach temperatures up to 200°F for the Standard Built-In model and up to 257°F for the High Watt Built-In model. It is important to note that Hatco is not responsible for any counter damage caused by the heat from the shelf.
