I was never able to get a lock bar for it; called snap-on and spoke to my dealer... I am assuming this is a situation where these parts were never things that were "field repairable" (just things like drawers, sliders, locks, linkage etc.). The lock bar was probably ripped out to be secured in a manner; that the military felt was more secure. The lock bar was installed and spot welded at the factory; if I could get the part for the current bluepoint line, I'm pretty sure it would work. I also think that these look like the Williams Industrial boxes... IDK if I will ever be able to repair mine; I'm sure someone who is good at metal work, could make me one. For now it just has our shop computer workstation on top of it and holds various things that I am not worried about be secured.
The welds I think on the inside are not secure; as the top most corners flex, I'm sure this thing has been through the ringer and it has had been hit, moved around allot. I guess if you had access to a spot welder; it could all be straightened, re welded, put back to a ridged and repaired condition with the fabrication of a lock bar... I don't have the tools or the skill... so we are just letting it be as is.
