Hi, so just for viewers, those are two 42" units, so clearly no issue installing a 24" patch panel, however if you want to put a 24" panel in a 28" panel that also is not a problem, I dont have a photo but you can vertically mount it, normally as close to the side as you can, there are angle brackets that support it, a link for those brackets is below, a pair is around $20

Thank you I saved one of your earlier Posts on the brackets , I am leaning more towards less ports still working it out .
