I ordered top case ends for a KH860 knitting machine. They arrived a day before the estimated date, and are excellent. I have fitted them already; they were easy to do and they fit the case perfectly. All the holes for the case screws and mushroom fittings line up, and there is a compartment in the left end for the extension rails to be secured, exactly as in the original. I am so pleased, and would recommend both the product and the seller.
