Earthing?

[Lectrician]

A TRS gland in the bottom would be required on this one.

This is an older model from a couple years ago, and is essentially two grid modules. A DP switch module and a fuse module, no flex outlet. As it stood there was no cord restraint.

Later versions look very much like the white logic FCU's inside the enclosure and the flex would exit the front, under the lid.

Not clear from the photo - there could have been clips on the flex starting a couple of inches below the enclosure.
