I have a question on an option and my last amend is Monday (2 days). The question on cargo storage rails

I haven't actually seen these, but I like options. My original build included this. I see they stand proud compared to the stock rings, but they move around, and I'm wondering if they can be removed when not in use. Do they get in the way? At 150, the money isn't significant, I'm strictly concerned about function and options. Does anyone have these (or seen them), have any experience, or maybe give me some direction good or bad. Thoughts are appreciated

 

I did one of these instead. I don't regret it. There isn't a lot of space in a 110 and having raised bars/pucks would be limiting with large flat items, cases of drinks, etc.
