My son pushed the chains that open up my radiators back in through the
cover. I can't get to the covers without disconnecting them from the
wall. They seem to be plastered in. Is there any other way for me to
retrieve them or use some other kind of makeshift thing to keep them
open. They can be pushed open from the front through the vents.
