The 18188 RTC uses an 18 in high by 18 in wide by 8 in deep footprint with a 16 gauge carbon steel shell, delivering a robust base that resists impacts and environmental wear. This structural integrity translates to reduced panel damage and fewer maintenance events, supporting reliable control housing in demanding industrial spaces. The NEMA 3R rating, UL 50 and CSA C22.2 compliance, plus a weather-conscious rain hood and heavy-duty butt hinge, provide dependable protection against moisture and incidental exposure while keeping doors and components securely enclosed for long service life. A hinged cover with key locking offers controlled access, while embossed thru holes and 9 bottom knockouts simplify installation and future cable runs, saving field time and minimizing retrofits. The painted ANSI 61 gray finish helps maintain a clean, professional appearance across installations, reducing touch-up costs and simplifying inventory management. Compatibility with surface mounting lets installers leverage existing mounting surfaces and fast-track deployment in electrical rooms or equipment yards. These features collectively improve installation efficiency, regulatory compliance, and total cost of ownership for control infrastructure projects.
