This is great for holding steeping grain and hops for the intermediate kits. You need the big 24x24" bags for this though - the smaller bags don't but around the hole. For a really slick setup, buy a 4" tri clamp to clamp the bag onto the flange. OBK doesn't have these clamps yet (hopefully soon?), but you can buy these from some other US online stores.
