Thomas Betts 2256-TB Liquidtight Elbow Cord Grip

Product Description

The THOMAS BETTS 2256-TB is a liquidtight elbow strain relief cord grip designed to secure and protect electrical cables at conduit entry points. Built from iron, this elbow-style fitting provides mechanical strain relief while maintaining a liquidtight seal around the cable jacket. It accommodates cables with an outer diameter ranging from 0.625 to 0.75 inches and threads into a 1-inch NPT fitting. Electricians and maintenance technicians install this fitting where a 90-degree cable entry angle is needed and where protection from moisture, oils, or washdown environments is required.

This cord grip is suited for use in industrial, commercial, and heavy-duty residential electrical installations where liquidtight conduit systems are specified. The elbow configuration is particularly useful in panel knockouts, junction boxes, and equipment enclosures where straight cord grips would create excessive cable bending or stress. Its iron construction makes it appropriate for environments that demand greater durability than plastic alternatives.

Key Features

• Elbow shape allows 90-degree cable routing without sharp bending stress
• Liquidtight design seals against moisture, oils, and contaminants
• Accepts cables from 0.625 to 0.75 inches in outer diameter
• 1-inch NPT thread size for standard conduit knockout compatibility
• Iron construction for durability in demanding industrial environments

Compatibility

Designed as an OEM-style replacement or direct-install fitting for liquidtight conduit systems using 1-inch NPT threaded entry points with cable outer diameters between 0.625 and 0.75 inches.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements for liquidtight fittings and strain relief. De-energize the circuit and disconnect power to the enclosure before removing or installing cord grips. Thread the fitting hand-tight into the NPT knockout, then tighten with an appropriate wrench — do not overtighten iron fittings as thread damage can compromise the liquidtight seal. Verify cable jacket is fully seated and clamped within the grip before restoring power.
