Masonry Box System Benefits
Masonry boxes provide permanent, secure mounting for electrical devices in concrete and block construction where standard wall boxes cannot be used. The embedded installation creates a flush, professional appearance while providing superior mechanical support for devices. The steel construction ensures the box maintains its shape and alignment even under the pressure of concrete pours and masonry installation.
Why Choose Steel Construction?
Steel masonry boxes offer superior strength and dimensional stability compared to plastic alternatives, especially important during concrete pours where significant pressure and weight can deform lesser materials. The Eaton Crouse-Hinds steel construction ensures your electrical installation maintains proper alignment and provides reliable device mounting for decades of service, backed by over 100 years of electrical innovation and contractor trust.
