USB Type-C Port Blocker Security lock with Metal Extraction Key

Specifications

• Interface Compatibility: USB Type-C (Female Receptacle)
• Material: Machined Metal Alloy
• Security Mechanism: Flush-fit insertion, requires custom extraction key (included)
• Protection Type: Dust-proof, Anti-tamper, Anti-debris
• Operating Environment: Indoor / Outdoor (Hardware protection)
• Compatible Platforms: Any device with a standard Type-C port (Raspberry Pi 4, ESP32 Dev Boards, Laptops, Mobile Devices, Industrial PLCs)

Minimum hardware to get started:

• Device with a female Type-C port (e.g., Raspberry Pi 4, ESP32 board, or laptop) : to insert and secure the blocker.
• Included Extraction Key : absolutely necessary to remove the flush-mounted blocker, as it cannot be pried out by hand or standard tools without causing damage.

Safety Warnings:

• Inspect Before Insertion: Ensure the Type-C port is completely free of dust or debris before inserting the blocker. Pushing the blocker into a dirty port can permanently compress conductive debris against the interface pins.
• Key Retention: Store the extraction key securely. Because these blockers mount completely flush, losing the key makes removal extremely difficult without damaging the host device's port casing.

Key features 

• USB Type-C Port Protection : Blocks unused USB-C ports to help prevent unauthorized connections.
• Durable Metal Construction : Strong metallic design for reliable, long-term use.
  Custom Removal Key – Special key allows authorized users to easily remove the blocker.
• Dust & Access Protection : Helps keep unused USB-C ports clean while restricting unwanted device access.

Accessories
Included in the Box:

• 10×Type-C Port Blockers
• 1× Custom Security Extraction Key

Frequently Asked Questions

• Will this fit any standard USB Type-C port?
  Yes, the blockers are machined to standard USB-C receptacle dimensions and will fit any compliant female Type-C port on laptops, phones, or development boards.
• Can I use this on a Raspberry Pi 4?
  Yes, it fits perfectly into the Type-C power port of a Raspberry Pi 4 when it is not actively being powered via that port (e.g., if powered via PoE or GPIO).
• Does this work with micro-USB or USB-A ports?
  No, these blockers are specifically designed exclusively for the USB Type-C form factor.
• Will it fit if my device is inside a case?
  It depends on the case thickness; the blocker is designed to sit completely flush with the metal rim of the port itself, so thick cases might make key insertion difficult.
• Does inserting the blocker trigger any electrical connection?
  No, the blocker is completely passive and does not bridge any power or data pins.
• Can it short out the pins inside my device?
  No, the internal design is carefully shaped to avoid bridging the delicate pins inside the Type-C receptacle.
• Is it safe to leave in a device that is powered on?
  Yes, it is entirely safe to leave the blocker installed while the device is powered on and operating.
• Do I need to orient the blocker a certain way before inserting?
  No, like the Type-C standard itself, the blocker is reversible and can be inserted right-side up or upside down.
• Does the key require a specific orientation?
  Yes, the key must be aligned with the dual slots visible on the face of the inserted blocker to hook the internal mechanism.
• Can I remove it with tweezers if I lose the key?
  It is extremely difficult and highly discouraged, as attempting to pry it out will likely permanently damage the device's port.
• Does this require any software configuration?
  No, this is a purely mechanical, physical security solution.
• Will my OS detect that a blocker is inserted?
  No, because the blocker does not bridge any data pins or present an electrical load, the operating system will not detect it.
• Can I use this to disable the port via software instead?
  This product provides physical blockage; if you need software-level disabling, you must configure that separately in your device's BIOS or OS.
• Why won't the key pull the blocker out?
  Ensure the key is pushed all the way in so the locking pins fully engage with the slots before pulling straight out.
• The blocker feels too tight to insert, what should I do?
  Do not force it. Inspect the port with a flashlight to ensure there is no compacted dust or bent pins preventing insertion.
