This is a new cast iron spout retaining nut that are made to fit the old Enterprise hand crank Sausage Stuffers and a lot of the other stuffers that look like the one in the picture, to hold the stuffing horn or tube onto the stuffer. IT WORKS WITH THE METAL STUFFING HORNS AS WELL AS THE 3 PIECE PLASTIC SET that i also list on Ebay. So if you can't find yours or brought one without the stuffing tube holder this nut is what you need. It will fit the 2 Qt. 4 Qt. 6 Qt. or the 8 Qt. stuffers.It works with the metal or the plastic stuffing tubes or horns, the hole in the nut for the tubes to go through is 1 1/8" so it should fit most tubes that are sold. I also have the 3 piece set of HD tubes listed on Ebay that will fit this nut.Please ask about combined shipping if you need the tubes also. I ship the same day payment is received so ts no waiting to make your sausage. Please email me with any questions. SAUSAGE STUFFER SHOWN IN PHOTO NOT INCLUDED.
