This wok ring, also known as a wok stand, is a metal ring meant to be used with a wok when cooking on a cooktop or grill. It keeps the round-bottomed woks in place while cooking. This ring functions as a heat trap, potentially causing damage to the burner grate and burner head. Furthermore, it may be installed by placing it on top of your burner and then placing your round-bottomed wok on the wok ring.
