Overview

The NSI Industries 290-RT Combination Coupling (SKU: 290-RT) is a patented, raintight solution designed for seamless transition between 1/2" Rigid or IMC raceways and 1/2" EMT conduits in both wet and dry locations. This coupling is UL-listed for wet location use, ensuring reliable performance even in harsh environmental conditions. The patented design simplifies installation by accommodating slight misalignments, reducing labor time and minimizing the risk of 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's durable construction ensures long-lasting performance, while its compact size and versatile compatibility make it a practical choice for electrical contractors and maintenance teams. Unlike standard couplings, the 290-RT eliminates the need for additional sealing compounds or complex installation procedures, streamlining project timelines and reducing material costs. Whether used in new construction, renovations, or maintenance projects, this coupling delivers a secure, weatherproof connection that meets industry standards for electrical conduit systems.
