Hi..

having never seen one I'm wondering how the breast bars that can be collapsed from the outside of the box work...


I've seen photos where there's definitely a bracket with some sort of release mechanism on one side (the ramp/near side on the ones I've seen) do they usually have the same on the other side? Can't really see the need for it to drop at both sides but I might be missing something

thanks
