USB-A Port Blockers 4-Pack

This set contains four physical blockers that fit standard USB-A ports to stop unauthorised flash drives or peripherals from being connected. It is intended for IT administrators and security-conscious users who need a simple hardware barrier against data theft or malware introduction.

Key-Locked Installation

Each blocker is inserted and removed only with the supplied reusable key, which also stores three spare blockers inside its body. The mechanism requires no software or drivers; the only common issue is misplacing the key, which would leave installed blockers permanently locked in place.

Four Blockers Per Key

The package provides exactly four blockers and one matching key, so a single key controls all included units. Buyers needing to secure more than four ports simultaneously will require additional packs.

Questions about this item

How do I verify the U2BLOCK-A-KEY blockers are properly locked into my USB-A ports?

Insert each blocker using the reusable security key until it clicks into place; the blocker will then physically prevent any USB-A peripheral from being inserted, confirming it is seated and locked.

What does the 4-pack include and is any extra hardware needed?

The package contains four USB-A port blockers, one reusable security key with internal storage for three blockers, and a quick-start guide; no additional tools or accessories are required.

Should I choose this 4-pack or a different quantity for my needs?

This U2BLOCK-A-KEY pack provides exactly four blockers and one key; if you need to secure more than four USB-A ports simultaneously, you will need additional packs.
