The PATA conduit reference points to such usage in South America.

Everything about them points to retrofit work.

ERICO used to have an entire suite of cheesy clips oriented towards running EMT immediately above a T grid -- junction boxes included.

They never made economic sense during a TI.

But I can certainly see them being used by service electricians for this or that....

As for myself, if I had to pull circuits during a service call -- above a soft lid -- I'd go with MC virtually every time.

I can't say as I've ever run across one -- installed or otherwise!
