Kannästor Grinder owners, look over here. Your unit already comes with a lifetime warranty, and the patent-pending design allows you to change the sifting screen with almost zero effort. If your screen has seen enough action, you’ll want to replace it with a new one. And we’re here to make that easy for you. You can choose between the following sizes: 1.5 inches, 2.2 inches, and 2.5inches. With that in mind, know that all 2.2 inches screens are compatible with grinders of the same diameter, including the GR8TR V2. They’re available in two mesh options - 60 mesh monofilament or 60 mesh stainless steel, so take your pick.
