Since the original question was not answered - no, it will not work with the current Ridgid rails. It will work if the Ridgid saw is used on a compatible rail though.
To my knowledge, from major brands, the Festool FS/2, Makita and the new Milwaukee rails use the same groove patterns allowing for accessories compatibility.
I see more and more makers "switch" to the FS/2 profile as the time moves on. It is clear the FS/2 profile is becoming a sort of an industry standard.
Besides the Mafell/Bosch system that is sufficiently different to have its own major benefits, I do not see a point in investing in weird rails like the Ridgid and then fighting the accessories struggle.
You are much better off moving to Milwaukee (if on tight budget) or better the FS/2 rails. Definitely for any saws which are compatible with the FS/2 system.
