This false bottom is designed to sit above the spigot of the 15 gallon Heavy Duty Kettle for easy wort removal. These bottoms are sturdy and will allow you to turn your kettle into a mash-tun, or you can use it as a screen to filter out whole hops.Constructed from type 304 stainless steel with 3/32 perforated holes on 5/32 centers. They come with welded on stainless legs (1.75" tall) and a handle for easy removal. Has a diameter of 17 11/16 inches. Same concept as a bazooka screen but less chance of clogging.
