Overview

The ABB B121ADJH One-Gang Adjustable New Work Outlet Box is a precision-engineered electrical enclosure designed for new construction installations where space and adjustability are critical. Constructed from durable PVC, this blue outlet box delivers 21 cubic inches of internal volume—providing ample room for wiring, outlets, switches, and electrical components in compact spaces. Its compact dimensions of 3.65 inches in length, 2.25 inches in width, and 3.32 inches in depth make it ideal for tight wall cavities, stud bays, or retrofit scenarios where standard boxes won’t fit. The standout feature is the horizontal adjustable bracket, which allows electricians to position the box precisely during installation. This adjustability ensures perfect alignment with drywall surfaces, eliminating the need for shimming or recutting studs. The bracket’s design accommodates horizontal movement, enabling fine-tuning for flush mounting in uneven or irregular framing conditions. This reduces installation time and ensures a professional, code-compliant finish. Built for reliability, the B121ADJH meets stringent electrical installation standards and is suitable for residential, commercial, and light industrial applications. Its PVC construction resists moisture, corrosion, and chemical exposure, ensuring long-term durability in demanding environments. The box includes standard knockouts for conduit or cable entry, supporting flexible wiring configurations. With a UNSPSC code of 39121309, it integrates seamlessly into ABB’s comprehensive line of installation products, offering consistency in performance and compatibility across projects. Whether you’re roughing in a new home, upgrading an office, or installing electrical systems in a retail space, the B121ADJH provides the adjustability, durability, and space efficiency required for modern electrical infrastructure.
