Adjustable Hardware on Underground Strut Rack Family
If you change one of the supports on the underground strut rack family to back to back strut, the hardware for it to attach doesn't change. It stays as a 1" bolt which will no longer reach through the strut to the strut nut in the strut its attaching to. It would have to be a 2-1/2" bolt to reach. I know this is small but it does make the BOMs incorrect for these situations.
