I just got a 16gal square cooler to turn into a lauter turn. I bought a round false bottom but it will not fit. I saw somewhere on the internet, but can not find it again, a cooler just like mine with a metal peice with holes that was perfect for the false bottom. But I dont know what kind of material it was. Does anyone know the picture and website of which I saw mabe. Or does anyone have an idea of what it could have been?
