SummaryClips can be placed along the aluminum extrusion and then the conduit routed through or attach the clips to the conduit and then attache them to the aluminum extrusions, either way this little clip works great. Edit: 5/5/2016 Added the clip with the hood. This one was so that I could route the wires in the 2020 extrusions channel and then cross over using the 3/8" conduit. The hood makes the transition nice and clean.
