I am redoing my basement, and also considering redoing the handrail into the basement. The original handrail was just a round piece of wood held to the wall with brackets. But some of the staircase does not have a wall so 2 2X4's were installed vertical to the ceiling to allow anchoring the bracket. I wanted to install balusters, but am not sure how this is done being there is not vertical wall to anchor the handrail too, and then you lose the handrail to anchor the baluster into too. See the picture below. If the handrail hits the ceiling area, I will have several feet of space I am not sure how to fill. Does anyone have a similiar basement they can show a picture?
