Evidence Lockers That Protect Case Integrity
Purpose-built evidence lockers for police departments, forensic labs, and government agencies. Pass-through, refrigerated, and drying cabinet configurations that maintain chain of custody from intake to disposition.
What Are Evidence Lockers?
Evidence lockers are specialized secure storage units designed for law enforcement agencies to receive, store, and transfer physical evidence while maintaining an unbroken chain of custody. Unlike general-purpose lockers, evidence lockers are engineered with tamper-evident features, access logging, and configurations specific to forensic requirements.
Modern evidence locker systems include pass-through designs (front deposit, rear retrieval), refrigerated compartments for biological samples, HEPA-filtered drying cabinets for wet evidence, and electronic tracking that creates court-admissible audit trails for every item handled.
Evidence Storage Solutions
From temporary intake to long-term preservation, evidence locker systems cover every stage of evidence handling with purpose-built configurations.
Pass-Through Evidence Lockers
Officers deposit evidence from the front; property room staff retrieve it from the rear through a secured door. Eliminates direct officer access to the evidence room and maintains a clean chain of custody.
Refrigerated Evidence Lockers
Temperature-controlled compartments for biological evidence, DNA samples, and perishable items. Maintain required storage temperatures from 2°C to 8°C with digital monitoring and alarm notifications.
Evidence Drying Cabinets
HEPA-filtered ventilation systems for drying wet or blood-stained clothing and evidence without cross-contamination. Controlled airflow preserves DNA integrity while preventing mold and degradation.
Temporary & Short-Term Storage
Individual locking compartments in various sizes for intake processing. Officers secure items during booking without entering the evidence room — multiple door sizes accommodate firearms, electronics, and oversized items.
Chain of Custody Tracking
Integrated barcode, RFID, or electronic access logging for every locker transaction. Automated audit trails record who opened each compartment, when, and for how long — court-admissible documentation.
Long-Term Secure Storage
High-density shelving and vault-grade locker systems for cases requiring extended evidence retention. Configurable for firearms, narcotics, and high-value items with restricted access controls.
How Evidence Lockers Work
A controlled, auditable workflow from the moment evidence is collected in the field through final disposition — every step documented, every transfer logged.
Evidence Intake
An officer submits evidence through the front of a pass-through locker or into a designated intake compartment. The locker door locks automatically after deposit, and the system logs the officer, time, and case number.
Secure Transfer
Property room technicians access deposited evidence from the secured rear side of pass-through units. Each transfer is logged electronically, maintaining an unbroken chain of custody with no overlap between depositor and retriever.
Cataloging & Storage
Evidence is barcoded, photographed, and assigned to appropriate long-term storage — ambient shelving, refrigerated lockers, or drying cabinets depending on item type and preservation requirements.
Retrieval & Disposition
When evidence is needed for court, lab analysis, or release, authorized personnel check it out through the tracking system. Every movement is recorded until final disposition — return, destruction, or release to owner.
Why Evidence Lockers Matter
Protect Case Outcomes
Improperly stored evidence can be challenged and excluded in court. Evidence lockers with documented chain of custody remove the basis for defense challenges to evidence handling procedures.
Meet Accreditation Standards
CALEA, ILEA, and state accreditation bodies require documented evidence handling procedures. Modern evidence locker systems generate the audit trails and access logs these standards mandate.
Reduce Liability
Lost, contaminated, or mishandled evidence exposes agencies to lawsuits and public scrutiny. Secure locker systems with electronic tracking eliminate human error in the evidence handling process.
Maximize Space Efficiency
Evidence rooms are perpetually short on space. High-density locker configurations, compact shelving, and modular systems maximize storage capacity within existing footprints — deferring costly facility expansions.
Types of Evidence Lockers
Different evidence types require different storage conditions. A complete evidence management system combines several locker configurations to handle everything from firearms to biological samples.
Pass-Through Lockers
The standard for modern evidence rooms. Officers deposit through front-facing doors; evidence techs retrieve from the secured back. Available in single-door, multi-door, and mixed-size configurations.
- Sizes: 12×12 to 24×36 compartments
- Front deposit / rear retrieval
- Keyed, combo, or electronic locks
Non-Pass-Through Lockers
Single-access lockers for temporary holding during booking or smaller departments without dedicated evidence rooms. Front-access only with individual compartment locks and master override.
- Sizes: 12×12 to 18×24 compartments
- Front-access only
- Individual and master keying
Refrigerated Lockers
Self-contained refrigeration units maintaining 2°C–8°C for biological evidence, blood kits, and perishable items. Digital temperature monitoring with alarm alerts for out-of-range conditions.
- Temperature: 2°C – 8°C
- Digital monitoring & alarms
- Lockable individual compartments
Drying Cabinets
HEPA-filtered forced-air systems that dry wet evidence — bloodstained clothing, weapons recovered from water, soaked documents — while preventing cross-contamination between items.
- HEPA filtration
- Adjustable airflow
- Separate drying compartments
Who Uses Evidence Lockers
Any agency that collects, stores, or processes physical evidence needs secure, compliant storage. Evidence lockers serve organizations from small-town police departments to federal investigative agencies.
Police Departments
Municipal and city police departments of all sizes use evidence lockers for daily intake processing, temporary holding during booking, and long-term case evidence storage. Pass-through configurations are the standard for departments processing more than 50 items per week.
Sheriff & County Offices
County-level law enforcement agencies with distributed substations require consistent evidence handling procedures across multiple locations. Standardized locker systems ensure chain of custody compliance regardless of which facility processes the evidence.
Federal & State Agencies
FBI, DEA, ATF, and state investigative agencies require high-security evidence storage with advanced access controls, environmental monitoring, and audit-grade logging. These installations often include narcotics vaults and firearms lockers alongside standard evidence storage.
Forensic & Crime Labs
Laboratories processing DNA, toxicology, and trace evidence need climate-controlled storage, drying cabinets, and contamination-free transfer workflows. Lab-grade evidence lockers integrate with laboratory information management systems (LIMS).
Built to Law Enforcement Standards
Evidence lockers are not off-the-shelf products. They are purpose-engineered for the unique demands of forensic evidence handling — from the gauge of the steel to the type of locking mechanism.
- Heavy-gauge welded steel construction (14–16 gauge)
- Anti-pry door frames and tamper-resistant hinges
- Individual compartment keying with master override
- Electronic access control with audit trail logging
- Powder-coat finish rated for institutional environments
- ADA-compliant configurations available
- Modular designs for phased installation and expansion
- GSA contract and cooperative purchasing availability
