Stir Fry Holder Chrome Plated Steel Wok Ring D.Line Chinese Round BottomThis ring is suitable mainly for an electric stovetop when using a round bottomed wok, as it stabilises the wok on the burner. It also helps to conduct the heat around the wok more evenly. It can also be used with a flat bottomed wok to diffuse the heat from the bottom of the wok and prevent food from burning. For best results use the wider end around the wok. Colour Silver Shape Round Construction Chrome Plated Steel Dimensions H 4. 5 cm Top
