How do pass-back and drop-slot lockers work?

Pass-back lockers allow technicians to return items securely to officers or labs, with doors that open from one side at a time. Drop-slot lockers enable officers to deposit small evidence bags quickly with one-way access that prevents tampering or retrieval.

Can these evidence lockers expand storage capacity for my facility?

Yes. Mobile compression shelving and modular evidence storage systems can increase storage capacity significantly without expanding your physical footprint and can be combined with digital or refrigerated evidence lockers.

Evidence Lockers for Law Enforcement & Government

Evidence lockers help agencies protect chain of custody from intake to retrieval. Our solutions include non‑pass‑through, pass‑through, refrigerated, digital formats, and charging-enabled intelligent evidence lockers. Your facility can choose evidence lockers with keyed or keyless access, audit logging, and configurable compartments for weapons, kits, and bulky items. We design to your space: freestanding, wall‑recessed, or modular banks to streamline bookings, reduce handling, and document every interaction for court‑admissible records.

Police using temporary evidence lockers in a secure room — Ensure full custody control with wall‑mounted and pass‑through lockers.

Police stations depend on fast, reliable evidence handling that keeps officers and technicians separated while preserving chain of custody. Pass‑through lockers install between booking and evidence rooms so officers can deposit items without entering secure storage.

Technicians retrieve items from the opposite side under controlled access, and all locker actions can be logged for compliance. These systems reduce handling errors and protect against tampering or lost property.

Digital pass-back evidence locker with keypad access — Maintain legal chain of custody in court‑adjacent evidence zones.

Courts and government offices often handle sensitive evidence coming directly from law enforcement agencies. Evidence lockers provide a secure buffer between incoming departments and court storage teams, reducing direct handoffs.

Options such as refrigerated compartments support biological evidence or narcotics that must remain sealed and stable during transfer.

Public safety evidence lockers with multiple small compartments — Provide fast, controlled evidence storage for campus and mobile teams.

Transit security offices and campus police departments need compact, modular storage for daily evidence drop‑offs. Our lockers fit small station rooms, command centers, or mobile trailers.

Pass‑through and non‑pass‑through options support 24/7 operation with clear logging and configurable layouts.

Pass-through keyless evidence lockers with digital keypad — Use refrigerated lockers for biohazards, narcotics, and forensic materials.

Some evidence requires refrigeration for legal validity or safety. Refrigerated evidence lockers keep narcotics, blood samples, and biological materials at controlled temperatures within secure compartments.

Lockable, trackable, and available in various sizes, these lockers are ideal for forensic labs, medical examiner facilities, and narcotics units.

Temperature‑controlled, secure compartments
Biometric, RFID, or PIN‑based access
Audit logging for traceability

Officer accessing pass-through evidence lockers — Organize and protect evidence inside secure property rooms.

Evidence rooms benefit from structured, secure locker banks with labeled compartments, pass‑back functions, and traceable retrieval. Non‑pass‑through lockers are ideal for internal storage, giving clerks easy access while limiting handling risk.

Configure by size, material, and lock system to improve efficiency and meet agency protocols.

Evidence locker with secure drop slot — Securely store and preserve evidence from station to courthouse.

Now available with onboard power and USB charging ports for seized digital devices such as phones, tablets or laptops, keeping them powered until they reach the forensic lab.

Only technicians can remove items from the secure rear side. With one way in and one way out, tampering is reduced and security is enforced.

Honest Results

““Thanks Craig! We really appreciate you pulling some strings to get the high density files installed. The library shelves are already loaded and ready for the Attorneys to move in! The HD files look great! This was a challenging project and it’s been such a relief to have your knowledge and support. Most of all, thanks for making us look good.”

“What I love about SSG is that you seem to have a product for about everything related to storage, you’re flexible with design options, you’re quick to respond, and perhaps most of all you always have CAD drawings that I can use in my drawings which makes my life easier. If there’s somebody else out there that does what you do, I don’t know who they are.”

“I searched high and low for a heavy-duty cabinet that was new, attractive, had drawers that could support more than 100 lbs., and was reasonably priced. I was running out of time when I found your website, it was a lifesaver!”
