When it comes to transporting detainees, safety and reliability are non-negotiable. At Diamond Truck Body Distributing, we specialize in designing and upfitting prisoner transport vans that meet the rigorous demands of law enforcement, correctional facilities, and government agencies throughout California and beyond.
Engineered for Maximum Security
Every prisoner transport van we build is designed with one goal in mind: secure containment without compromise. Our systems feature:
- Heavy-duty steel containment cages
- Tamper-resistant hardware and locking systems
- Full interior partitioning between driver and detainee areas
- Reinforced walls, ceilings, and doors
These features ensure detainees remain securely separated while protecting officers and drivers at all times.
Officer Safety & Ergonomic Design
Transporting individuals in custody requires more than just containment—it demands efficient workflow and officer safety. Our vans are built to support real-world use with:
- Clear sightlines for constant monitoring
- Easy-access entry and exit points
- Non-slip flooring and step systems
- Optional camera and surveillance integrations
We design each layout to reduce risk, improve control, and streamline transport procedures.
Durable, Low-Maintenance Construction
Diamond Truck Body prisoner transport vans are built to withstand daily use in demanding environments. We utilize:
- Corrosion-resistant materials
- Easy-to-clean interior surfaces
- Ventilated compartments for airflow and compliance
- Noise-reduction design for quieter transport
The result is a long-lasting, low-maintenance solution that performs reliably over time.
