Vandal Proof Recessed Single-Gang Outlet Security Box with Hitch Lock
Product Overview
The AA-EB-1G-HL-LP is a low-profile, high-security outlet enclosure designed specifically for recessed single-gang electrical box applications. Crafted from 12-gauge stainless steel and secured with a cross bar hitch lock system, it provides reliable protection against vandalism, tampering, and weather exposure in high-traffic public environments. The compact 2½” depth makes it ideal for tight spaces or walls where flush-mounted or recessed installations are critical. Rear and bottom conduit access points ensure compatibility with existing infrastructure, while the removable backplate allows easy setup and service access.
Note 1: Hitch lock is included.
Note 2: Keyed alike available upon request.
Note 3: Receptacle outlet is not included with the housing. Most boxes on the market should fit, but for a known receptacle box that was tested to fit, Click here for 1 Gang - Weatherproof Electrical Outlook Box and Cover.
UL Certification & Code Compliance
Our heavy-duty enclosures are engineered strictly as secondary architectural physical security hardware. The AA-EB-1G-HL-LP 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.
