This is the KITINTO expandable exhaust vent cover from Three Coins. It simply sits on the grill's exhaust vent to effectively guard against dirt. It can also be used as a temporary place to put seasonings and cooking utensils. It's an expandable type that can be adjusted to fit the width of your stove. Size: H3 x W46-87 x D10.5cm Color: Ivory I tore the packaging when opening it, but it's new and unused.
