Not all black clips which fit over rails are the same. The governing factor is whether the rail in question has a ridge/shoulder around the outside. If it does the Performance Tool clips are correct (they have the inner shoulder which rides on the shoulder of the rail). If not, the Wrights are correct. They are not interchangeable.
Sometimes you can tell from photos whether or not they have the shoulder. Some brands on Amazon with the shoulder are Ares, Olsa, ABN, Mechan.
Some without the shoulder (last time I looked) are Vim, Wright, Armstrong, Matco, Snap On, Goliath, Craftsman, Wiha, Bergen, Inertia Tools, Casomanl, Horusdy, Sedy, Mayouko, Makitoyo, WXTools. But look carefully at the photos, sometimes things change.
