The bit in my last post was used for a test-only driver adjustable component...which was ultimately unsuccessful. I was able to snag it from the bin on a "tidy Friday" lab cleanup. I was able to incorporate it into an overkill drawer latch mechanism:

Here's an overall view:

The latch rod is 3/4" round, with hooks bent out of 3/8". Most of the hooks just catch the backs of the drawers, but the top two drawers were too close together to do that, so the 2nd drawer from top got a loop for the latch hook to catch.
The top and bottom arms have bronze bushings in them, and pivot on 3/4" shoulder bolts:

The lever pokes through a slot in the side of the cabinet to actuate the mechanism:
