Arlington EB1111 11 11 3.5" Heavy-Duty Non-Metallic Enclosure Box, NEMA3R, Gray

Protect sensitive monitoring, security and power backup equipment with the Arlington Industries EB1111 heavy-duty non-metallic enclosure box. Designed for both indoor and outdoor use, this NEMA 3R-rated enclosure delivers reliable weather protection when mounted with the hinge on top, keeping surveillance cameras, access control, and backup power components safe from rain and environmental damage. The compact 11 x 11 x 3.5" footprint fits tight installations while still providing room for a removable back plate that simplifies installation and on-site maintenance—swap batteries or service electronics without removing the entire box. Built from UV-rated, non-metallic plastic, the EB1111 resists corrosion and impact, making it a low-maintenance alternative to metal cabinets. Installers will appreciate the 1/2" and 3/4" knockouts for easy conduit runs and the front knockout for a cam lock or padlock latch (cam lock sold separately) to secure equipment against tampering. Ideal for security, surveillance, networking and power backup applications, the Arlington EB1111 combines durability, convenience and security. Add this enclosure to your next deployment to protect critical devices and streamline maintenance.
