The Lindy HDMI Port Blockers are useful little devices that can be used to physically prevent access to HDMI ports. With the HDMI Port Blocker Key, the user can quickly block any open device ports and easily prevent users from connecting cables, devices or inserting foreign objects without permission. 

The semi-permanent HDMI Port Blocker is made up of a moulded plastic blocking cap that plugs securely into the HDMI port with a special insertion key. The blocker latches into the port just as a normal HDMI cable would and remains in place until removed using the insertion key.

Designed to help protect against unauthorised access to a network or system, as well as preventing unintentional or malicious damage to ports. It can also act as a visual cue, showing inactive or disconnected ports, ideal for use in schools, office or other public sector environments. 

To use, simply attach a blocker to the key and insert it into the HDMI port. Release the sliding mechanism on the key to leave the blocker in place. To remove, simply insert the key back into the blocker and pull away.

Security Note: The Port Blockers will only act as a basic physical & visual deterrent to tampering. It will not prevent a determined attacker, intent on gaining physical access to a HDMI port.
