I don't know. I sold my old Horn cabinet with a smaller opening as I had originally used it for my Viking 500....it was too small for the D1. It was an older air-lift that you had to pull the little plastic loop on the air-lift. It also just had one little leaf on the left side that opened up. She asked me how much I wanted and I said $50. I could tell she was a bit surprised at the high cost but agreed as it was in good shape. A week or so she called me and said she loved having her machine in a cabinet and that she had gotten a real bargin.
