Silver Grip TCF Series nonmagnetic, corrosion-resistant straight aluminum fittings are designed for installation in Class 1 Gas and Vapor environments, without the use of tools. This fitting provides efficient strain relief for cable entering enclosures and raceways in hazardous locations. The tapered neoprene bushing and O-ring seal out moisture and dirt. The chuck grip exceeds the pullout value required by NEC.Note: Tray cable and portable cord applications comply with IEC requirements for Class 1, Zone 2, and Zone 1 locations, respectively, when used with enclosures containing no arcing or sparking devices. For enclosures with arcing or sparking devices, TCF fittings must be used in combination with a certified Class 1 hazardous location sealing fitting.
