Can you guess what these are for?

A quick design I knocked up the other day to get the workshop in the shed up and running. I bet you can't guess what they do.

Spoiler:

The power cable from the house to the shed needs to run up a wall and then across to the shed and down again. I need something to manage the transition from vertical to horizontal to reduce strain on the cable. If it just hung from the cable clips it would pull them out and also bend itself too sharply. These fellas allow a tight fixing to the wall and the shed and manage the curvature of the cable.

There should be more filleting and bevelling but, to be honest, I couldn't be bothered to do it.
