I own a 52 gallon extreme cooler which I use as my hybrid biab mash tun. I bought this as a screen that allows me to filter the mash (through a mesh bag that sits on this as a false bottom) and allows for an easier sparge. It also enables better recirculation too via my rims setup. Bent the sides down to match my cooler size then cut the folds down to size. Careful on the oils that this thing comes laced with on arrival - clean it well before you use it for food (or beer in my case).
