Thomas Betts IHEF2-1 Extension Adapter Aluminum

Product Description

The THOMAS BETTS IHEF2-1 is an aluminum extension adapter designed to extend or reposition electrical enclosure knockouts, hubs, or conduit entry points in wiring and junction box applications. Constructed from aluminum for durability and corrosion resistance, this adapter ships complete with a plug gasket and screw, providing the hardware needed for a finished, secure installation. Licensed electricians and electrical contractors working on panel, junction box, or enclosure work will find this a straightforward OEM-style fitting solution. The included plug gasket supports a sealed connection, and the fastening screw locks the adapter in place once positioned correctly.

This extension adapter is suited for use in residential and commercial electrical installations where conduit entries or enclosure knockouts require repositioning or extension. It is appropriate for indoor and outdoor enclosure applications where aluminum construction meets environmental and code requirements. The gasket inclusion makes it applicable in installations where a degree of sealing at the entry point is required. Electricians performing panel work, pull box installations, or enclosure modifications will find this adapter a practical add-on fitting.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the electrical enclosure or panel before beginning any fitting work. Use appropriate hand tools to seat and tighten the included screw without overtightening, which could damage the aluminum threads or gasket. Verify the gasket is properly seated before completing installation to maintain the intended seal at the entry point.
