I was watching an old movie 'Come and Get Me' with Lloyd Bridges and noticed the jail cell had bars with two ridges. I recalled from my youth seeing the same type bars and had wondered why the ridges. I searched the net with no answer to my question. See picture attached, feedback welcome, thanks.
Keep them from turning in the cross bars?
Maybe they didn’t weld all joints to leave slop in case of foundation settling.
