Thanks for that confirmation, bloody annoying, I must have mentioned the model 2 or 3 times and was told yes they're for NC24.

I hope they'll take them back.
I've learned a valuable lesson, must be sure before ordering over the phone.

Thank you again, I will now source the right parts

The NC21/24 share the same frame so many sellers assume that everythign is interchangable.

Theres quite a few subtle differences between the models (and some not so subtle differences)

If your on the phone to people you want the Silver hangers not the black ones :-)
