16 gauge steel construction with ANSI 61 gray finish delivers durable, corrosion-resistant service in harsh environments, reducing replacement cycles and maintenance costs while matching industrial aesthetics. The 8 in height, 8 in width, and 12 in length provide ample space for typical panel wiring, and embossed thru holes simplify mounting while eliminating unneeded field drilling. No knockouts and a screw cover secured by a flange with plated screws reduce edge exposure and improve enclosure integrity, cutting installation time and potential contamination ingress. CSA Certified and UL Listed credentials support compliance with global electrical standards, while the NEMA 3R rating adds weather and corrosion resistance for indoor and protected outdoor installations. Compatibility with Eaton B-Line accessories ensures scalable, modular installation and predictable performance across multiple enclosures and control cabinets.
