Product Overview
The AA-EB-1G-HL is a rugged, surface-mounted electrical security enclosure built to protect critical single-gang power access points in high-risk environments. Featuring a heavy-duty cross bar hitch lock system for superior tamper resistance and 12-gauge stainless steel construction, it provides unmatched protection against vandalism, theft, and abuse. With integrated spray-deflective housing, conduit entry from both the rear and bottom, and a removable backplate that supports recessed or surface installs, it is ideal for schools, parks, transit hubs, military facilities, or anywhere security and durability are essential.
Note 1: Hitch lock is included.
Note 2: Keyed alike available upon request.

UL Certification & Code Compliance
Our heavy-duty enclosures are engineered strictly as secondary architectural physical security hardware. The AA-EB-1G-HL 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.
