There aren't 2 screws on a NTE5C.
Agreed, the face plates clip of, it was designed so that people without any tools can gain access to the test socket, which makes sense.
I am not a fan of them due to you can knock the face plates off too easy.
I hope they don't fit them for FTTP that get FVA
I know there was talk of having the FV Face plates made, but not seen one yet.
