When the knob is tightened, the roller stones apply pressure to the stone base and through shearing action, the particle size of the ingredients are broken down. \n\n\nSuitable for all Premier Chocolate Refiners (countertop models), this part is made of hard plastic and stainless steel. Available in black or white.\n\n\nThis upgraded newer model will not work with older model lids since the center opening in the lid needs to be at least 2.25\" (approx 5.7cm). The older model lids can be cut by the customer to fit the newer top lock knob.\n\n\n\n\n\n\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0287/1738/products/Flower_Top_Lock_Nut_500.jpg?v=1640654240"],"price":20,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:21.046Z"},"share_url":"https://firestarter.network/l/lst_N8BMsQEu","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
