They are called unistrut spring nuts. Unistrut is also known as Kindorf.

Hi Jim

I think I have now answered my own question by looking for a web page to show 
you. The channel on the cabinet is basically the same as:

although it is part of the welded cabinet in my case. The channel nuts are 
basically the same as:

So clearly they do exist, but I can't find a stockist.

Please forgive me if this is the wrong forum.

I have been happily building an amplifier and other things into an old 19" 
BC transmitter cabinet. The cabinet is quite old but in good condition. 
Unfortunately, it did not come with the rear door, and I am not very happy 
about having lethal voltages around with no protection. So I thought - 
easy - I will fit panels to the rear which will be useful for connectors 
The cabinet has fixing channels in it which are basically unistrut, and 
there are horizonal ones at top and bottom which take standard (spring) 
channel nuts. So that bit really is easy. There are also vertical channels 
at the back which is where I want to fix my panels and these are much 
smaller. To use those I need channel nuts which are approximately 10.5mm 
across the flats. I know that these (did?) exist as I have the three that 
were used for the original door. But I need more and as far as I can see, 
they make hens with teeth seem pretty common.
Any suggestions?
