Keep Your Manholes Secure With The LockDown Security Device
If anything enters your facility from below ground, the answer is yes. If these holes aren't secured with the LockDown Device™, then your infrastructure is vulnerable. You control access to your site, your buildings, your data rooms, even your phones, but access points to your communications lines or other critical delivery systems are covered by an unsecured, removable lid.
