Octagon Box System Benefits

Octagon boxes provide superior fixture mounting capabilities compared to standard rectangular boxes. The eight-sided design distributes mounting stress more evenly, while the larger size accommodates more complex wiring configurations. The adjustable bar system eliminates the need for precise measurement during rough-in, allowing contractors to position fixtures exactly where needed during finish work.

Why Choose Steel Construction?

Steel construction offers exceptional durability and structural integrity for fixture-rated applications. Unlike plastic alternatives, steel boxes provide reliable grounding continuity and can withstand the mechanical stress of heavy fixtures and ceiling fans. The integrated AC/MC clamps are engineered specifically for armored cable applications, ensuring secure connections that meet code requirements while reducing installation time and material costs.
