889B 889B Cast-Iron Floor Box

Cast-iron floor box for on-grade applications in commercial environments, supporting low-density power or communication requirements

The Wiremold 889B is a cast-iron floor box engineered specifically for on-grade applications in high-traffic commercial environments. This solution is designed to bring power or communication services directly to workstations in open-space layouts, such as retail facilities, hotels, and financial institutions. Unlike the stamped steel version used for above-grade mounting, the 889B cast-iron construction is built for durability in concrete floor installations. The 880 Series supports a wide range of industry-leading activations, including brass, brushed aluminum, and nonmetallic options. This specific 889B unit provides a robust foundation for low-density service needs with a depth of 4.8 in (12.2 cm) and a width of 4.8 in (12.2 cm). This TAA compliant box is a standard choice for integrators managing floor-based connectivity in large-scale commercial office spaces.
