USB-A port blockers for physical security

The Tripp Lite U2BLOCK-A10-RD pack contains ten red blockers that fit standard USB-A ports. Each blocker prevents unauthorised flash drives or peripherals from being connected. A separate Tripp Lite U2BLOCK-A-KEY security key is required to install and remove the blockers.

Replaces open ports with a locked barrier

The jump is worth it when an organisation must stop data exfiltration or malware introduction through exposed USB-A sockets. Software policies can be bypassed, but a physical blocker remains effective even if the operating system is compromised.

Fits any standard USB-A socket on PCs.

The nickel-plated and polyoxymethylene construction meets RoHS and REACH standards and carries TAA compliance. Ten blockers in the pack secure multiple workstations, and the red colour makes protected ports easy to identify during audits.

Questions about this item

Does each blocker use a single USB-A connector to seal the port?

Yes, every blocker has one connector that fits a standard USB-A port and locks in place with the matching security key.

What is the correct way to install a blocker so it cannot be pulled out by hand?

Insert the blocker into the USB-A port, then push the Tripp Lite U2BLOCK-A-KEY security key into the blocker until it clicks; the key locks the blocker so it cannot be removed without the key.

Will the red colour or the nickel-plated contacts degrade and require replacement over time?

The polyoxymethylene body and nickel-plated contacts are rated for the product's lifetime warranty; no scheduled replacement is needed unless a blocker is physically damaged or lost.
