900 mounts at LaScilla in Chile

A number of cameras mounted on the AP 900 mounts at LaScilla for site survey work.

Those sharp corners on the concrete piers instill fear into those of us who do unattended imaging.
There might be unintended tracking/slewing into those corners.
Do the mounts need any special preparation for use at LaScilla?
