Have a similar pair that I bought from a different company.
Overpriced and quite convenient.
I used to just run bolts up through my offroad light tabs, drill near the top for a small padlock and use wingnuts to tighten down.
Cheap, works great and more secure that these aluminum doodads.
Got hot for the ones like you are looking at and now they sit in a parts box.
Save your money, unless bling is your thing.
