Thomas Betts TCF050 40AL Strain Relief Cord Grip 1/2 Npt

Product Description

The THOMAS BETTS TCF050 40AL is a straight strain relief cord grip designed for use in Class 1 gas and vapor environments. It accepts cables from 0.25 to 0.4 inches in diameter and threads directly into a 1/2-inch NPT conduit entry point. The body is cast aluminum, offering corrosion resistance and durability in demanding industrial and commercial installations. This fitting mechanically secures the cable jacket at the conduit entry, reducing stress on internal connections and maintaining the integrity of the conduit system. Electricians and instrumentation technicians install this type of fitting wherever cables enter enclosures in hazardous-rated locations.

This cord grip is suited for installations in Class 1 hazardous locations where flammable gases or vapors may be present. Typical applications include industrial control panels, motor junction boxes, pump stations, and process equipment enclosures that require rated cable entry fittings. The straight profile makes it a practical choice where a direct, in-line entry into the enclosure is needed without angled or flexible intermediate fittings.

Key Features

• Straight profile for direct in-line cable entry
• Accepts cable diameters from 0.25 to 0.4 inches
• 1/2-inch NPT thread for standard conduit knockouts and hubs
• Aluminum construction for lightweight corrosion resistance
• Provides mechanical strain relief to protect internal terminations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for enclosures and conduit systems requiring a 1/2-inch NPT straight cord grip rated for Class 1 hazardous gas and vapor environments.

Installation Notes

Installation should be performed by a licensed electrician familiar with NEC Article 501 requirements for Class 1 hazardous locations. De-energize the circuit and verify lockout/tagout procedures are complete before opening any enclosure. Thread the fitting hand-tight into the NPT entry, then tighten with an appropriate wrench — do not overtighten aluminum threads against dissimilar metal hubs. Verify the cable jacket is captured securely in the grip body before closing the enclosure.
