What I've bought (from researching this forum) was:
MBS Generic grommets type C (shared grommets) & I (single grommets). They're both the "long" version & some people recommend to trim them with a razor to size (longer grommet can be cut, short cannot be extended ). According to my research, this fits 99% of racquets out there (the other 1% is U-shaped grommets found in newer racquets).
Note that I haven't received the above items (they're still in transit) so it's only info that I found from digging around in this forum.
Another idea is to salvage grommets from old/ broken racquets & put them into the Cab
