IKEA Besta - Adapter for cover cap screw hole

With the IKEA Besta modules, only the top one is attached to the wall. This is the only place where the supplied cover caps can be attached. For example, if you had a display case underneath, you could look directly at the holes in the back wall. This adapter is used to subsequently attach the cover caps supplied. The adapter can be easily inserted into the hole. The cover can then be attached.
