Hello,

I have got a cupboard hung to the wall of my kitchen. There's a small
gap between the cupboard and the door, so whomever fitted it has
filled this gap with a small corner unit: its just a few shelves big
enough to put a few photos or ornaments on.

I would like to remove this corner unit but I don't know how. The big
cupboard has two metal "boxes" that protrude in each top corner but
other than that there are no obvious fittings. There are certainly no
fittings on the corner unit. There were three small screws attaching
the side of the cupboard to the side of the corner unit but I have
removed those and the corner unit is still firm.

I think that the corner unit is secured to the big cupboard but how?
Glue? How can I remove the corner unit?

Thanks,
Stephen.
