Cages for double straps, do they exist?

I had metal ones with one gate for a while. They make a horrible noise when scraping and they shape the strap into this funny triangle. I bought these and I'm very happy with them.

No more noise and they keep a nice shape for getting your foot in easily.

I have a similar ones, they have been for more than 8 months in the polo bike, no problems at all, I will recommendent them
