Electure,
What's the story in the 3rd picture?.
I see a lot of cables heading upwards(or downwards) over the edge of a (sharp?) metal edge?.
Is it common practice to have Data connection blocks out in the open like that?, it would be the first time I've seen them without some sort of a cover or enclosure over them.
I can't say I'm a fan of all of them joints and missing covers in the 4th pic either. [Linked Image]
