Blocker
Locker 7
Pass-Thru
The first permanently installed, dual-door faraday evidence cabinet. Devices are deposited on one side of the wall and retrieved on the secure side — RF-shielded and continuously powered throughout. No shared space. No direct handoff. No compromised chain of custody.
Electrician Required
Evidence Comes In.
Evidence Stays
Separated.
Most chain-of-custody failures don't happen in the lab. They happen during handoff — when intake personnel and forensic staff share the same space, the same locker, or the same moment. The Pass-Thru eliminates that moment entirely by building the separation into the wall itself.
Officer Drop-Off
Continuously Powered
Forensic Retrieval
Built Into the Wall.
Separated by Design.
The Pass-Thru's defining feature is its dual-door architecture. Each compartment has a door on both sides of the wall, allowing intake and retrieval to occur completely independently — without shared space or direct handoff between personnel.
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 Pass-Thru keeps every device individually locked, RF-shielded, and continuously charged — while maintaining physical separation between intake and forensic personnel.
Patrol drops a device at 2 AM on a Saturday. The investigator retrieves it Monday morning from the secure side — fully charged and still shielded. No lockout. No remote wipe. No lost evidence. The wall did the work.

Never Lose a
Device to a
Dead Battery.
Every Blocker Locker 7 Pass-Thru 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 Pass-Thru 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.
Window Charge &
Shield Faraday Bags
The product that makes the entire forensic pipeline possible. Every Blocker Locker 7 Pass-Thru ships with 7 Window Charge & Shield bags — one stationed in each compartment. A dual-sided USB filter built into the bag wall passes power and data without RF leakage.

Every Detail Engineered
for Chain of Custody
The Blocker Locker 7 Pass-Thru 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. Built into the wall. 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 compartment has a door on both sides of the wall. Intake and retrieval occur independently — intake personnel and forensic staff never share the same space or moment.
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 Pass-Thru has no power cord or outlet plug. A licensed electrician connects it directly to the building's electrical system during installation. This means no one can accidentally unplug it — power is always on, every bay is always charging, 24/7.
Basic usage instructions on the intake side walk any officer through the correct intake process — step by step — without forensic training. An additional in-depth instruction sheet is included.
Each of the 7 compartments has its own unique numbered lock. After locking, officers drop their bay key into the built-in key drop slot. Investigators retrieve keys from the secure side. Master keys provide supervisor access.
MySpool sends SMS and email notifications if power to the unit is lost. A power indicator light on the main cabinet confirms system power status at a glance.
Every Blocker Locker 7 Pass-Thru is built in the United States and available as a Berry Compliant product for government and military procurement.
From Field to Lab.
Every Device Stays Live.
The Blocker Locker 7 Pass-Thru is Step 3 in the Mission Darkness evidence workflow — the permanent, wall-mounted hub that bridges field seizure and forensic extraction.
