VEVOR Square Fire Pit Wind Guard, 19" x 19" x 6" Glass Flame Guard, Fire Wind Guard Fence with 5/16 Inch Thickness Clear Tempered Glass and Non-Slip Feet, for Propane, Gas, Fire Pits Pan/Table

Hi I’m trying to order one of these and I’m wondering if it should sit on the outside edge or if it should sit in the bevel of the Firepit itself 19 inches gets it perfectly inside the bevel of the pit but it won’t have any space under the glass and I see there is feet so I’m wondering if it should go on the table around the pit? Can someone please help me thanks
