Ikea curtain tracks (Staple Hill BS16)

I have no idea which windows I even imagined I'd use these on... they don't seem an appropriate size for any in this house.
So these are 2 brand new, still in their shrink wrap (save for 2 spots where being left in a slightly damp shed had had an unfortunate impact on the nice compostable packaging, so I've despatched those to the bin) IKEA Vidga curtain tracks with - to the best of my knowledge) all bits and pieces untouched.
And one curtain track of a different kind (definitely Ikea, but the wrapping is gone so I don't know which specific product it is) with 9 curtain hooks.
Prefer they go together.
