Arlington EB1212-1 Electronic Enclosure Box
The Arlington EB1212-1 is a non-metallic enclosure measuring 12″ x 12″ x 4″. It is manufactured from heavy-duty, UV-rated plastic designed to withstand outdoor exposure. The enclosure is lockable with a latch that accommodates a padlock, providing secure access control for power backups, network devices, or security components within a debris-free environment. Suitable for indoor use as well, this model supports mounting options consistent with common electrical installations. Its durable exterior helps resistance to weathering while maintaining a clean appearance in utility spaces.
Arlington EB0708-1 Electronic Enclosure Box
The Arlington EB0708-1 enclosure is compact, with dimensions 7″ x 8″ x 3.5″, made from UV-rated non-metallic material. It provides debris-free protection for small electronics, backups, or security devices. The box is lockable with a latch that accommodates a padlock for added security. Its non-metallic construction offers electrical isolation properties and resistance to corrosion, suitable for tighter installation spaces while maintaining outdoor viability and weather resistance for everyday electrical applications.
Arlington EB1212BP-1 Enclosure With Back Plate
The EB1212BP-1 adds a back plate to the standard EB1212 footprint, enhancing mounting flexibility. This 12″ x 12″ x 4″ non-metallic enclosure is designed for secure installation of power boxes and security devices in a debris-free environment. It meets typical outdoor or high-traffic indoor applications, with UV-rated plastic and weather-resistant properties. The hinge-on-top design (where applicable) supports reliable access and maintenance while preserving the enclosure’s integrity against environmental exposure.
TICONN Waterproof Electrical Junction Box IP67 ABS Plastic
The TICONN enclosure is an IP67-rated ABS plastic box designed for waterproofing and high humidity environments. It features a hinged cover with stainless steel latches for easy operation and reliable seals. The package includes mounting plates and cable glands (3/8″ NPT and 1/2″ NPT) to simplify external wiring. With its robust ABS construction, it delivers electrical insulation and impact resistance, making it suitable for outdoor electrical installations, panels, and protective housings against weather intrusion.
LeMotech Junction Box IP65 ABS Plastic Project Enclosure
The LeMotech IP65 junction box provides weatherproof protection for outdoor electronics with IP65 sealing. Constructed from durable ABS plastic, it delivers reliable electrical insulation and impact resistance, making it suitable for sensor housings, control modules, and small electrical assemblies exposed to wind, rain, and dust. The enclosure emphasizes ease of installation, with drill-friendly features and compatibility with external cable glands to secure wiring for robust outdoor setups. This option suits projects where moderate protection and a compact footprint are required.
Buying Guide: Non-Metallic Enclosures — Key Purchase Considerations
When selecting a non-metallic enclosure, consider these factors to ensure a suitable match for your project:
- Protection rating: IP and NEMA ratings indicate weather and ingress protection. Choose IP67 for immersion tolerance (outdoor) or IP65 for splash resistance (less extreme exposure).
- Material and durability: ABS and UV-rated plastics offer corrosion resistance and light weight, while some models include UV stabilization for sun exposure and impact resistance for outdoor use.
- Size and mounting: Verify internal dimensions, mounting plates, and whether back plates are included. Ensure compatibility with existing enclosures, panels, or wall mounting.
- Security features: Lockable latches and padlock compatibility help control access to sensitive components.
- Accessibility and maintenance: Hinged covers, removable back plates, and clear labeling simplify maintenance workflows and future upgrades.
- Environmental suitability: Consider exposure to direct sunlight, rain, dust, and temperature fluctuations, and select UV-rated or weatherproof materials accordingly.
- Cable management: Look for included cable glands and knockouts; broader protection is achieved with multiple glands and proper sealing.
- Cost-to-protection balance: Non-metallic enclosures typically offer cost savings, but verify that the chosen model meets the necessary safety and durability requirements for your application.
For applications requiring robust outdoor protection, IP-rated ABS or UV-stable plastics with locking mechanisms provide reliable performance. Inside facilities or controlled environments, smaller non-metallic enclosures with padlock-ready latches can securely house power backups or electronics without the weight of metal housings. The five products highlighted here span compact to larger formats, enabling a range of protective solutions for residential, commercial, and light-industrial settings.
