I just installed a 12" on my Ultimate. This is a high quality product. The only complaint I have is there was not a drill bit with my order, that slowed me down until I could find what the drill bit size was supposed to be.
Hey Pelican,
Man I'm really sorry about the drill bit being missing. We used to put them in with nothing on the tip but they could poke through the package. Not sure if we forgot to put one in or if it "poked through" and escaped

It's still a fairly product so it's possible we missed putting it in there. Especially if I packaged it

That's why Vicky doesn't let me package much
Now we dip them in a coating that protects the sharp tip so it can't poke through the poly packaging.
I guess you figured out it's a 1/8" drill bit. I'd be happy to mail you one if you still need it.
We make occasional mistakes but ALWAYS make it right. If you ever have a problem don't hesitate to let me know.
