Two other things I forgot to add. These are in the original CG-1500 cases that apparently are no longer available.
I only have one power lead used with a jumper to tie the two sides together since my total amp draw is very small per channel. I used mostly LEDs, but had some channels with just a single 100 count incan string on them. A second input can be added by removing the jumper and adding an additional input power cord if you have high amperage draw per channel or total amps per box.
two units pending sale completion, two units still available
