I have only allowed 3 stars, but I bought this for the Titan stand. Other reviewers warned about the danger of a plastic stand scoring or the inside of the bell, so I bought this sock to protect against that. It works on the Titan stand, but only with modifications. The large end of this sock is too small; it cannot acquire the Titan's base. We had to separate the material, and even with that, it's still tight. No big deal, but this stand and sock are for a 12-yo boy to use, and he doesn't like the sock. Again, that may lead to scoring the inside of the horn.
