Octagon Box System Benefits

Octagon boxes provide superior mounting strength compared to standard round boxes, with eight mounting points distributing load more effectively. The larger internal volume accommodates complex wiring connections, while the adjustable bar system eliminates the guesswork in fixture positioning during rough-in electrical work.

Why Choose Steel Construction?

Steel construction delivers the structural integrity required for fixture-rated applications, providing long-term reliability under load and vibration. The material's strength ensures code compliance for ceiling fan installations while maintaining dimensional stability over decades of service. Eaton Crouse-Hinds steel boxes resist deformation during installation and provide secure mounting for professional electrical connections.
