Overview

The ABB WMCC7940 Deluxe Strain Relief Cord Grip is a heavy-duty cable entry solution designed for secure, watertight connections in industrial and commercial installations. This straight male cord grip features a 2-inch National Pipe Thread (NPT) entry, providing a robust threaded interface for conduit systems or panel penetrations. The unit accommodates cable diameters ranging from 1.81 to 1.94 inches (45.9 to 49.3mm), ensuring compatibility with a wide range of heavy-gauge cables and cords. Engineered for durability, the WMCC7940 incorporates a deluxe strain relief design that prevents cable pull-out, twisting, and mechanical stress at the entry point. The internal clamping mechanism distributes pressure evenly across the cable jacket, reducing the risk of insulation damage and maintaining long-term seal integrity. This design is particularly suited for applications where cables are subject to vibration, movement, or environmental exposure. The straight male configuration simplifies installation in tight spaces or where directional routing is required. The NPT thread ensures a secure, leak-resistant connection when mated with compatible fittings or conduit systems. This cord grip is ideal for use in control panels, junction boxes, machinery enclosures, and outdoor electrical installations where environmental protection is critical.
