Rail-less here. Works well with built-in bookend.
When I went searching for file cabinets (mid-1980s), I didn't like what I found at Wal-Mart, K-Mart, et al. So visited an office supply company (expensive!) and asked about quality old file cabinets. Was told to find an old Hon, Art Metal, or Steelcase unit.
Then knowing what to look for, I found an old Hon (legal-sized, 4 full-extension drawers, roller-glides, sliding/locking rear bookend) in a locksmith shop. Wasn't cheap, but much less than new and much better built. Locksmith installed a lock reasonably.
It's made a few cross-country moves (just lock it and go) and the movers have not been able to damage it.

(Knock wood.)
