The breadth of the line encompasses conduit sizes from 1/4 to 4 in with fittings offered in machined aluminum, nickel plated aluminum, steel, stainless steel, nylon and Valox®. For applications known for their severe conditions, such as oil and gas, marine, food and chemical processing - RSR cord grips are available in nickel plated aluminum. Providing exceptional corrosion resistance and high wear resistance, nickel plated connectors also feature an attractive finish similar to that of polished stainless steel. Tuff-Seal™ RSR cord grips protect cable from damage and pullout and are used in conduit hubs or knockouts at the point where the electrical cable is to be terminated.
