I have not seen a standard on cabinets. I have gear in a wide variety of racks. Some of are real shallow. Some are deep. I use these to generically solve the sagging issue. https://www.amazon.com/dp/B00XXDJASY?ref=nb_sb_ss_w_as-reorder-t1_k1_1_11&=&crid=EFCM0EZP8BMA&=&sprefix=navpoint+ra NavePoint Universal 1U Rack Mount 4-Post Shelf Rail for Dell Compaq IBM HP APC - 33.5 Inches deep amazon.com Justin Wilson j2sw () mtin net — https://j2sw.com (AS399332) https://blog.j2sw.com - Podcast and Blog

Unfortunately, the posts are very flimsy, as these are some fancy cabinets with spacing on the sides for vertical patch panels, etc. We found that 2 post mounting of most Cisco devices (namely Cat 9500 1RU switches) are sagging quite bad. We’re used to the new server type rails that extend to support most reasonable distances front rails to back for 4 post mounting. However, for a Cisco ASA1001, there aren’t rails, but rather front and back ‘ears’ you use to hit both front and back posts. These would appear to not have any adjustability, the front to back post distance would seem to need to match the ears, I assume they don’t adjust placement on the router much. Is there a ‘standard’ distance between front and back rails that devices usually adhere to? Googling didn’t find an answer readily. These are 19” wide cabinets by the way. Thanks, Chuck
