I am trying to remove the shower bar brackets, I guess this is what you call them on a sliding shower glass door. The handles are a **** tone color. I was hoping to remove the hardware so I could paint them to update the look in the bathroom. The problem is there are screws to remove the bar but on both sides of the bar there are brackets that have no screw holes. I have no clue how to remove them, the hardware is only on outside of door. Not sure how to remove them without breaking the glass. Thank you for your help!!!
