No trunking? No problem.

There’s a reason that facilities told me they weren’t happy with many of the previous cabling contractors the school had used.
Here’s some bonus images off the McGuyver-like standoffs the installers created for the board rail itself, and evidence of how good their clean-up job was when they installed the board 4 years ago:
