The Heated Black Glass Shelf is a built-in shelf with a length of 72 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 available in different frame finishes and is cULus and UL EPH Classified, meeting ANSI/NSF 4 standards. The heated black glass shelf is made of approved foodsafe material, making it suitable for use on pass-through areas, buffet lines, and as hors d'oeuvre displays. It comes with a lighted on/off rocker switch and a 6-foot cord and plug for portable models. The thermostatically-controlled ceramic glass surface provides heat ranging from 100°F to 195°F for portable models. An optional angled food stop is available for portable models to keep the product on the heat zone. The shelf is designed to allow food products to be placed directly on the glass surface. It comes with an attractive trim mounting ring in stainless steel or Designer Black. The built-in models include a control box with a 3-foot conduit and a 6-foot cord and plug. They are recommended for use in metallic counters, but the suitability of other surfaces should be verified for temperature resistance. The Standard Built-In model can reach temperatures up to 200°F, while the High Watt Built-In model can reach temperatures up to 257°F. It is important to note that Hatco is not responsible for any counter damage caused by the heat from the warmer. Options available at the time of purchase include different sizes for portable models (24", 30", 36", 48", 60", and 72"), an angled food stop, and a Designer Black Powdercoated Trim Ring. The Built-In models offer additional options such as a unit without a trim ring, a built-in shelf with a recessed top, and different control box configurations. Non-standard colors for the trim ring and control bezel box are also available, but they are non-returnable. Overall, the Heated Black Glass Shelf is a versatile and reliable option for keeping food warm and displaying it attractively in various settings.
