Hey all, sorry I did mean to say ASR1001 (an X model to be exact). The 4 post mounting they show in a hardware mounting doc uses front and back ears, which I’ve never done: https://www.cisco.com/c/en/us/td/docs/routers/asr1000/install/guide/asr1routers/asr-1000-series-hig/asr-hig-1001.html#task_1205646 see figure 16 slightly down from there.
I do see some generic rails from TrippLite that probably would work, as well as shelves. I was hoping a standard depth that most vendors honored for 4 post existed, but it doesn’t seem likely. We’ll have a variety of PaloAlto, Cisco, Checkpoint, and others co-habiting.

All I have are 23" telco racks but I will say, the 23" extension ears from Cisco are serious and my router chassis' don't sag.

Front *and* back ears? I'm not sure what an ASA 1001 is (ASR?) but my experience with these boxes is that they have a single pair of ears which can be mounted front OR back. The heavier / deeper 1RU devices do tend to sag alarmingly. Is there a ‘standard’ distance between front and back rails that devices usually adhere to? If you're thinking of setting the front/back distance to accommodate a specific device, table 2 might be of some interest: https://i.dell.com/sites/doccontent/business/solutions/engineering-docs/en/Documents/rail-rack-matrix.pdf
