Shielded.
Charged.
Locked.
The centerpiece of every forensic lab. Seven individually locked Faraday compartments that keep seized devices live, RF-shielded, and continuously charged — from a 2 AM patrol drop to Monday morning extraction. No lockout. No remote wipe. No lost evidence.
Evidence Comes In.
Evidence Stays Alive.
Most evidence failures don't happen in the lab. They happen at the station, overnight, on a weekend — when no examiner is present and a device quietly dies in a drawer.
The officer bags it in a Charge & Shield Faraday Bag, drives to the station, and drops it into a locked Blocker Locker bay. Plugs in the USB. Goes home.
MySpool monitors power around the clock. If anything interrupts the charge, an SMS and email alert fire immediately — to whoever needs to know. The device never sees the outside RF environment.
The examiner takes the Charge & Shield bag directly to the BlockBox Lab XL. Opens the NeoLok seal with conductive gloves inside the enclosure. Connects to GrayKey. The device never left shielding until this exact moment.

Never Lose a
Device to a
Dead Battery.
Every Blocker Locker 7 ships with MySpool — a hidden power failure detector that monitors the unit around the clock and sends an immediate SMS and email the moment power is lost. When devices die overnight, passcode cracking fails and evidence recovery suffers. MySpool is the safety net that makes sure that never happens.
The MD Monitor app connects to the Blocker Locker 7 and the Forensic Crack Cabinet via built-in sensors, giving real-time visibility into device status, power health, temperature, and humidity — without opening a door. Works on iOS and Android. Manage multiple units across multiple locations from one dashboard.
The Station-Side
Link in the
Evidence Chain
Modern forensic tools like GrayKey and Cellebrite require seized devices to stay powered and live. The Blocker Locker 7 keeps every device individually locked, RF-shielded, and continuously charged — indefinitely — until the moment it's transferred to the lab.
Patrol drops a device at 2 AM on a Saturday. The investigator picks it up Monday morning, fully charged and still shielded. No lockout. No remote wipe. No lost evidence. Any officer can do the intake — no forensic training required.
Window Charge &
Shield Faraday Bags
The product that makes the entire forensic pipeline possible. Every Blocker Locker 7 ships with 7 Window Charge & Shield bags — one per compartment. A patented dual-sided USB filter built into the bag wall passes power and data without RF leakage. Every other product in the lineup depends on it.

Blocker Locker 7
Stand
The matching Locker Stand transforms a wall-adjacent cabinet into a complete, professional evidence station. Built from industrial-grade aluminum with a lockable storage compartment underneath — the finishing piece for any department that takes chain of custody seriously.
Every Detail Engineered
for Chain of Custody
The Blocker Locker 7 was built from the ground up to solve the real problems investigators face — from device intake through to lab extraction. Not adapted from general-purpose hardware. Not a modified charging station. Built for this.
The patented NeoLok magnetic closure opens and closes with minimal friction — critical when working with conductive gloves inside a forensic enclosure. Far less abrasion than Velcro-seal bags.
Each of the 7 compartments fits up to 2 Charge & Shield Bags simultaneously — both powered at once via dual USB receptacles. Purchase additional bags to support 14 devices in the same footprint.
Each Charge & Shield Bag includes a dual-sided USB filter that lets you switch from power to extraction tool without removing the device. An external cable lock prevents disconnection.
The transparent window on every included bag lets officers and investigators confirm device status, battery level, and screen state without ever opening the bag.
The Window Charge & Shield Bags transfer directly into the BlockBox Lab XL — no rebagging, no unsealing, no exposure. Connect to GrayKey via the RJ45 port. The device never left shielding.
A magnetic instructional sticker on the front of the cabinet walks any officer through the correct intake process — step by step — without forensic training.
Each of the 7 compartments has its own unique numbered lock with 2 keys. Four master keys provide supervisor access. A built-in key dropbox lets officers deposit keys after locking evidence in.
Each compartment supports 2 Charge & Shield Bags powered simultaneously. When additional bags are purchased, the same 7-compartment cabinet handles up to 14 devices.
Multiple Blocker Locker 7 units scale across a department. Each pairs with the Locker Stand for ergonomic height, additional storage, and an integrated key drop slot.
Field to Lab.
The Blocker Locker 7 is Stage 03 in a five-stage forensic evidence system. Each product hands off seamlessly to the next — RF seal intact, device live, chain of custody unbroken.
Faraday Bags
Device seized and immediately bagged. All WiFi, 5G, Bluetooth, GPS, and RFID signals blocked at the scene.
+ Battery Kit
USB filter passes power through the bag wall with zero RF leakage. Device charges continuously during transport.
Seven individually locked, RF-shielded bays keep devices live and charged at the station for days, weeks, or months. MySpool monitors power 24/7.
Lab XL
Charge & Shield Bag transfers directly in — RF seal never broken. Connect to GrayKey or Cellebrite via filtered RJ45, USB, and AC ports.
Cabinet
Up to 30 devices powered and secured while cracking tools run for days, weeks, or months. 8 Noctua PWM fans prevent overheating.
From Device Intake
to Secure Storage
Any officer, even without forensic training, can correctly process a seized device without compromising chain of custody.
Place the seized device into the Window Charge & Shield Bag stationed in the compartment. Connect via the included cable tip. Seal with the NeoLok magnetic closure.
Plug the compartment's shielded USB cable into the bag's outer USB port. Engage the cable lock. Confirm device status through the transparent window — no need to open the bag.
Lock the numbered compartment with its unique key. Drop the key into the front-mounted key dropbox. The device stays locked, live, and shielded indefinitely.
Remove the bag — RF seal intact — and carry it to the BlockBox Lab XL. Open the NeoLok seal inside the enclosure with conductive gloves, then connect to GrayKey or Cellebrite.

Works With Your Existing Tools
Compatible with all major forensic extraction platforms
If your tool requires a network or USB connection, the BlockBox Lab XL's filtered RJ45 and USB ports support it while maintaining full RF isolation.
We use faraday bags in the field, transfer to a Blocker Locker at the station, then use a BlockBox Lab XL for analysis, then the Forensic Crack Cabinet to keep phones powered during cracking. By keeping devices on and protected, we've had better success getting into the majority of devices we process very quickly.
