Made of heavy gauge perforated stainless steel, this false bottom will fit perfectly in a 6 gallon plastic bucket or some 5 to 10 gallon water coolers. 9" diameter with a 3/8" o.d. stainless steel hose barb. Attach plastic tubing to this barb to complete your lauter tun. Unlike plastic false bottoms that can float up during the mash because of the light weight, this false bottom will stay at the bottom of the mash vessel where it belongs.
