Overview

The ABB 68-HP-CI Cast Iron Flush Service Floor Box (SKU 68-HP-CI) is a heavy-duty solution for power, data, and AV installations in commercial and industrial environments. Engineered with a cast iron body and a 6-inch non-metallic collar, this floor box delivers 140 cubic inches of internal volume—one of the largest capacities in its class—while maintaining a flush, low-profile design for high-traffic areas. The 5-31/32-inch opening diameter accommodates standard devices, including duplex, GFCI, locking, hospital-grade, and isolated ground receptacles, as well as multi-media adapters for AV applications. Key features include dual conduit hubs: a 1-inch hub for power wiring and a 1-1/2-inch hub for data/communications, ensuring flexible configuration for mixed-load installations. The cast iron construction provides superior durability against heavy carts, cleaning equipment, and general floor traffic, while the non-metallic collar eliminates corrosion risks in metallic conduit systems. Installation is simplified with no leveling, gluing, or alignment required—cut the box to the desired height post-pour and secure with stainless steel retention barbs. Minimum concrete depth is 4-1/2 inches for flush mounting or 4 inches for furniture-feed applications. The 68-HP-CI is part of ABB Installation Products' Steel City® series, designed for universal compatibility with standard 3-gang devices and rectangular adapters. Its tool-less slide latch and flat-lying lid minimize obstructions during use, while the round design eliminates alignment constraints during installation. Ideal for slab-on-grade or metallic conduit setups, this floor box ensures reliable, long-term service for power distribution, data networks, and AV systems in offices, retail spaces, healthcare facilities, and educational institutions.
  • 140 cubic inches internal volume for ample wiring and device capacity
