I have a cheap ikea desk and the only underside I can hang on moves because it's part of the drawer, so I stuck my hanger sideways

It comes with screws for mounting and 3m double sided tape incase you don't want to damage your desk with holes.

Attached to the underside of a glass top desk, with supplied adhesive (cleaned area, attached & waited 24 hrs before use)

So east to install perfect for mounting under my glass top desk

makes my desk look much cleaner, nice secure adhesive

desk still feels sturdy as ever!

Now my desk is clean.
