Answered: Attaching to the top of the Hanging Bar

Since the hanging bar is hollow, does that mean it is legal to hook into the hollow portion of the pipe?
I’ve attached an MS paint drawing (Not to scale) if it’s hard to understand what I’m asking.

Yes, this is legal. <SG8> will be appended in the June 15th update to make it clear that attaching to the Hanging Bar is legal.
