I was having some discussion with someone about electrical signs and whether or not the devices you can buy to put on circuit breakers you can buy for a regular panelboard count as a "line-of-sight" external disconnect as stated under 600.6. I do believe that OSHA doesn't count those devices as disconnects because they can be removed "easily". NEC doesn't explicitly point that these don't count from what I can tell though. Can anybody shed light one way or another??

The locking device meets the intent of the NEC IMHO as long as it is within sight.

But, some loads require a local disconnect no matter what.
