Hardin Marine makes one. It actually says KE on top. They have it in black or polished but don't have a pic online. It is in the catalog. The part number is 755-5105 for the 1/4-20 and 755-5106 for the 5/16-18. Look at my website at the 750. I have one on the flame arrestor. Don't know how good you can see it, but it is a nice piece.
