Great catch, GLW. Thanks!
I totally forgot about that one. It's new this year.
And you are spot on about an extension piece, however I doubt that it's something that we would have manufactured. Frankly, I'm not sure the sales of such an item would warrant production (ordinarily, you'd think it would, but this is Chinese manufacturing, so we'd probably get way overcharged to something like that). That being said, it's a standard pipe size and thread, so I imagine it wouldn't be too hard for someone to make one on their own.
