Six-gang configuration optimizes space for multiple conduits, reducing panel footprint and enabling cleaner wiring in service entrances and equipment rooms. This translates to fewer enclosures on large projects and faster installation in tight wall cavities. The steel masonry box construction provides impact resistance and long-term durability, lowering replacement costs and maintenance needs in busy industrial environments. A generous 93 cubic inch capacity accommodates multi-wire assemblies, minimizing splices and simplifying cable management for better reliability and traceability. Knockout patterns—end, side, and bottom—offer flexible routing for 1/2 and 3/4 inch conduits, reducing on-site fabrication and fit issues. Compliance-focused design with NEC/CEC and UL certifications supports cross-border projects and procurement efficiency, while the 11 inch length and compact footprint suit standard masonry workflows. Weighing 2.3 lb, this enclosure balances rigidity with ease of handling during installation and retrofit projects.
