I am not even sure how to describe this thing - but this is a grip or holder for my glass tray in the toilet.
I think previously it was held by glue, but it has gotten loose and the tray slips off. I stuffed a cardboard below to create tension so the tray will stay. However, the area is constantly wet, hence the cardboard is prone to dissolving eventually and in danger of falling.
This is a link with the picture - picture speaks a thousand words!
What options do I have to repair it so the tray can be gripped by the holder again?
