Product Overview
The AA-EB-1G-OL outlet lock box provides simple, secure protection for single-gang duplex receptacle boxes in high-risk or exposed public environments. Constructed from heavy-duty 12-gauge stainless steel, this enclosure resists tampering, corrosion, and moisture intrusion. A removable backplate supports both surface and recessed installations, while ½” and ¾” conduit access points on the rear and bottom offer layout flexibility. Designed to be secured with a user-provided padlock, this durable model is ideal for schools, parks, military sites, apartment complexes, and commercial facilities.

UL Certification & Code Compliance
Our heavy-duty enclosures are engineered strictly as secondary architectural physical security hardware. The AA-EB-1G-OL does not house electrical wiring; it is designed to be mounted directly to the structural wall over your existing, fully compliant, UL-listed electrical box and its associated UL-listed cover. Because our product operates entirely outside the electrical system, it does not require an independent UL electrical listing. To comply with local Authority Having Jurisdiction (AHJ) bonding requirements (such as NEC 250), the stainless steel enclosure can be readily bonded to the equipment grounding conductor by your installing electrician.
