The 5 lb. Vertical Sausage Stuffer has a stainless steel base and cylinder and all metal gears. Clamp the stuffer to a table or counter top and crank out perfect sausage every time. Comes with 3 plastic stuffing tubes: 1/2", 3/4", and 7/8" ID (11/16", 7/8", 1" OD). Cylinder removes for easy filling and cleaning. Air valve release pushes air out the top instead of into the casing. If you are wanting to make snack sticks 19mm or smaller, you may want to get the 606A Stuffing Tube (sold separately).
