IMO just take the pic to the lighting store thay will tell you for sur e. Why are you worring about the pendants they can be wired in ignoring what ever track you have. If they are going into a track then to match visually is good. I need to see the space please t understand the need for all the track

Thank you- youre right, just trying for a qui face lift and hoping not to mess with wiring! appreappreciate yhe help though, I’ll pop in at a lighting store today

That is an H track. Yes, you can attach three pendants to the track instead of two. Make sure you buy pendants compatible with the H track; Amazon sells lots of them. You can also buy a track adapter (example) and wire pendants to the adapter.

Thank you!!
