Thomas Betts IHEF2-2 Extension Adapter Aluminum

Product Description

The THOMAS BETTS IHEF2-2 is an aluminum extension adapter designed to extend or offset electrical enclosure hubs, conduit fittings, or knockout connections in wiring system installations. Constructed from aluminum, the adapter offers a lightweight yet durable solution for adjusting fitting depth or bridging dimensional gaps in electrical assemblies. It ships complete with a plug gasket and mounting screw, giving installers the hardware needed for a complete installation without sourcing additional components. Licensed electricians and electrical contractors typically install this type of fitting as part of conduit or enclosure work on commercial and residential projects.

This extension adapter is suited for use in electrical enclosure, panel, or conduit fitting applications where standard hub depth does not align with the installation surface. It is applicable in both new construction and retrofit scenarios where fitting extension is required to achieve proper seating and seal. The included plug gasket helps maintain an environmental barrier at the connection point.

Key Features

• Aluminum construction for lightweight durability and corrosion resistance
• Includes plug gasket for environmental sealing at the fitting interface
• Includes mounting screw for secure assembly without additional hardware
• Compact form factor suited for tight enclosure and panel installations
• Package quantity of one adapter per unit for precise procurement

Compatibility

Designed as an OEM-style accessory extension adapter for use with compatible electrical enclosure fittings and conduit hub assemblies where depth extension is required.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize all circuits and verify the absence of voltage before beginning any fitting or enclosure work. Ensure the plug gasket is properly seated before tightening the mounting screw to maintain the integrity of the seal at the connection point. Do not overtighten the screw, as this may distort the gasket or damage the adapter threads.
