Place four screws into the node enclosure with the washer and strut channel nuts on the backside.

You can remove the strut channel nut spring to make installation easier.

Slide the node into the strut channel arm.

The washer should be on the outside of the strut channel and the strut channel nut should be on the inside.

Tighten the screws with a 3/8 inch wrench.

This is what the node looks like attached to two strut channel arms.
