J-CHANNEL house / eave clip for holiday lighting

I use 12mm RGB bullet pixels for holiday lighting on my house. And I install them into j-channel which is pretty common, but I didn't want to screw the channel itself to the house, because that makes repairs harder, or if I need to pull the channel down for any reason. This system allows the CLIPS to screw into the house / eave, and the j-channel just snaps into place, behind a tab you can release to remove the channel when needed.
