Does anyone know what the function of those wooden ballet barre looking things mounted to all the walls by the windows were....just like what it shown on the right side wall in this picture? I noticed them all over the adult building, and neither myself or my friend could figure it out.

They may have locked it but regardless the tunnels are extremely flooded and not worth going in as far as I'm concerned. Last I knew, the water was about waist deep and it could be worse now, that is just asking for disaster.
