This 3-in-1 electric warming tray features a modular design that lets you use one heating panel on its own or connect up to three panels for a warming surface up to 47" wide. It's perfect for keeping multiple dishes warm during family dinners, holiday gatherings, and parties. When you're finished, simply separate and stack the panels for compact storage. Its 10 temperature settings range from 104°F to 266°F, giving you flexible heat control for different foods. Independent controls for the left, middle, and right zones let you keep soups, side dishes, and other meals at different temperatures, or use the ALL button for consistent heating across every panel. The built-in 24-hour timer offers flexible heating control, while the default 2-hour auto-off helps prevent accidental extended use. A child lock helps prevent unintended adjustments, and you can easily switch between Fahrenheit and Celsius to suit your preference. This versatile warming tray does more than keep meals warm. Use it for dough proofing, thawing frozen food, melting chocolate, or gently warming milk. It works with a variety of heat-resistant cookware, including ceramic plates, glass dishes, stainless steel pots, cast iron pans, and foil trays. The tempered glass surface is waterproof, oil-resistant, and easy to wipe clean after meals. Four non-slip feet on each panel help keep the tray stable while providing insulation to protect your countertop or dining table.
