Beam protection?

Hi, so I have completed my simulator build but I used metal beams for the frame. Now the front two metal (side) beams that the screen is connected to are exposed. Would like any suggestions on what to use to protect these beams to prevent ricochet? I know GT uses these foam blocks/strips but I can't seem to find a place to get them.

Any help is greatly appreciated.
