Blocco porte USB Renkforce rf-USBBlocker-02 confezione da 10, argento

Renkforce USB port blocker rf-USBBlocker-02 pack of 10, silver provides a simple physical barrier for standard USB-A ports. The set contains ten silver port covers designed to be inserted into USB sockets to prevent unauthorized connection of flash drives, peripherals or charging cables. Made for office, education and public environments, these blockers are intended to reduce the risk of data loss, unauthorized file transfer and unwanted device access without modifying the host device.

Advantages

These USB port covers are compact, lightweight and finished in a neutral silver tone to blend with most equipment. The individual blockers are easy to insert and remove with minimal tools, offering a non-permanent security measure that does not affect port functionality when removed. Because they are passive physical devices, they do not require software or power and can be deployed quickly across multiple machines.

Suitable for

• Offices where control of removable media is required
• Schools and laboratories to prevent unauthorized device connections
• Public kiosks and shared workstations to limit tampering
• Home setups where USB access should be restricted for security or parental control

Key specifications

• Quantity: pack of 10 USB port blockers
• Colour: silver finish
• Port type compatibility: standard USB-A sockets
• Material: durable plastic construction for repeated insertion/removal
• Installation: push-in insertion, tool-assisted or manual removal

How to use

Align a blocker with the USB-A socket and press gently until it is fully seated to block the port. To remove a blocker, use a small flat tool or the supplied extractor if available, applying steady traction to avoid damage to the port or blocker. Deploy the covers on unused ports to limit physical access while keeping required ports available for authorized devices.

Recommendations

For best results, test one blocker on a non-critical device to confirm fit before installing across multiple systems. Keep removed blockers together in a labelled container to avoid loss and to enable quick reinstallation when access is required. Avoid forcing a blocker into damaged or non-standard ports.
