Extra piece on bar

Good morning. I can’t find anything on this and I’m curious. Why do some bars have a connection between the top and bottom of the bar at the very back end by the mounting holes? Thanks

Just a guess as I have never given it much thought. I would say different applications/saws. Some have 1 bar lock nut and a guide/support stud. Others have 2 bar lock nuts. The picco's that I have worked on only have 1 lock nut and a guide/support stud. jmho

Thanks for responding. Ya just not sure. The standard bar for my 025 has no support stud and it’s a dual lock nut system. My MS182 is a single nut and also no support stud. I also can’t see it being a 325 vs 3/8 thing as I’ve seen the support on some 325 bars and not on others. Weird

On A short bar it doesnt make much difference if the bar has the connection between the top and bottom rail on the back of it. I'm guessing someone removed it on some small bars to save a buck when making the bar.
