NEMA 4X Traffic Shelters

Traffic equipment, such as stop lights, traffic signals, and control systems, operate in challenging outdoor environments. Exposed to harsh weather conditions, extreme temperatures, and potential vandalism, these critical systems require robust protection to ensure reliable performance and public safety. DDB’s NEMA 4X enclosures provide a sturdy shelter for traffic-related equipment, offering a high level of durability and security. Their rugged construction and weatherproof features make them an ideal choice for safeguarding the sensitive electronics that keep traffic systems running smoothly.

One of the primary reasons NEMA 4X shelters are ideal for traffic equipment is their exceptional resistance to environmental factors. Rated for protection against rain, snow, sleet, and windblown dust, these shelters ensure that sensitive components remain unaffected by adverse weather. This is particularly important for traffic lights and control boxes, which must function consistently in all conditions to prevent disruptions in traffic flow. Additionally, NEMA 4X enclosures, acting as a protective shelter, are built to withstand corrosion, making them suitable for coastal areas or regions with high humidity, where salt or moisture could otherwise damage equipment.

Beyond weather resistance, these shelters provide rugged physical protection, which is crucial for traffic equipment located in high-traffic or urban areas. DDB Strong isn’t simply a unique catch phrase, all DDB shelters are constructed of Alumiflex®, a material that is much lighter than steel yet strong enough to rack the heaviest of electronic equipment. These enclosures can resist impacts, tampering, and vandalism. For example, stop light control systems housed in a NEMA 4X shelter are less likely to suffer damage from accidental collisions or intentional interference, ensuring continuous operation. The secure locking mechanisms and sealed designs further deter unauthorized access, protecting valuable electronics from theft or sabotage.
Many traffic control systems rely on intricate electronics that are susceptible to overheating or moisture-related damage. NEMA 4X enclosures, serving as a reliable shelter, can be equipped with thermal management systems, such as ventilation or heating/cooling units, to regulate internal temperatures. Their seals also prevent moisture ingress, reducing the risk of short circuits or corrosion. This ensures that traffic lights and related equipment remain operational, even during extreme heat, cold, or heavy rainfall.

DDB shelters offer versatility and customization, allowing them to meet the specific needs of various traffic applications. Whether housing traffic signal controllers, communication devices, or backup power systems, these shelters can be tailored in size, and configuration to accommodate different equipment types. Their compliance with strict industry standards ensures compatibility with municipal and federal regulations, making them a trusted choice for cities and transportation agencies.
