There is a small hole in the side of the mounting baseplate for a security screw we will be offering soon.
For you DIYers, here are the specs:
M5x20 fully threaded or 10 smooth + 10mm thread.
The head has to be 9mm diameter max to enter the small hole and sit flush/hidden. Ideally its a button head or shallow socket so it cannot be grabbed with pliers.
Also recommended that its a security type head.
We will offer a custom screw and bit during summer 2021.
