for a Cisco ASA1001, there aren’t rails, but rather front and back ‘ears’

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:
