TSI INOX Conduits presents our premium Stainless Steel Device Box and Cover, a high-performance electrical enclosure engineered for demanding installations requiring superior corrosion resistance, hygienic design, and reliable device mounting. Manufactured from premium SS316 (CF8M) stainless steel and featuring a stunning mirror polished finish, our device boxes provide durable, sanitary enclosures for switches, receptacles, and other wiring devices in food processing, pharmaceutical, chemical, and marine environments.
Device boxes are essential components used to wire devices such as switches and receptacles, act as pull boxes, and connect conduit sections . Whether you are installing electrical outlets in sanitary facilities, mounting switches in corrosive environments, or creating pull points for conductor installation, TSI's stainless steel device boxes deliver the quality, durability, and code compliance your project demands.
The combination of 316 stainless steel and mirror polished finish provides exceptional corrosion resistance in the most demanding environments, including chemical plants, offshore platforms, food processing facilities, and marine installations.
The mirror polished surface and stainless steel construction create a sanitary enclosure suitable for food-grade and pharmaceutical applications, where bacterial growth and contamination must be minimized.
The internal grounding screw and all-metal construction provide a reliable, low-impedance equipment grounding conductor path, maintaining electrical continuity throughout the raceway system.
Device boxes are designed to match conduit size for neat, compact installations, ensuring a professional appearance and consistent performance across the entire raceway system.
Device boxes provide easy access for future system changes, modifications, and upgrades, reducing downtime and simplifying maintenance.
Standard switch, receptacle, and GFCI cover options accommodate a wide range of wiring devices
