The version In the photo is and was used with a hose clamp mount on tube.
Can't say I ever experienced any issues with it moving or not being tight enough.
With that in mind depending on the mounting location, a little "movement" wouldn't hurt in a roll or flop. It would help prevent breakage if it has some give IMO.
But willing to make anything.
Should be able to cut some parts today. I think I have a couple of sheets of 1/8".
