Overview

The NSI Industries 290-RT Combination Coupling (SKU: 290-RT) is a patented, raintight zinc alloy coupling designed for direct transition between 1/2" Rigid Metallic Conduit or IMC raceways and 1/2" EMT conduits. Engineered for use in both wet and dry locations, this coupling meets UL Standard 514B and CAN/CSA STD. C22.2 No. 18.3 requirements, ensuring reliable performance in harsh environments. The coupling features a high-strength zinc alloy construction with a ball burnished finish for enhanced corrosion resistance and durability. With dimensions of 1.63" (A) and 1.06" (B), the 290-RT accommodates slight misalignments during installation, reducing labor time and minimizing installation errors. Its raintight rating provides superior protection against moisture ingress, making it ideal for outdoor, industrial, and commercial applications where environmental resistance is critical. The coupling eliminates the need for additional sealing compounds or complex installation procedures, streamlining project timelines and reducing material costs. Supplied in standard packaging of 100 pieces per box and 25 pieces per unit, the 290-RT is a practical choice for electrical contractors and maintenance teams requiring a secure, weatherproof connection that meets industry standards for electrical conduit systems.
