Leviton Telcom L7751-100 Npt Strain Relief Connector

Product Description

The LEVITON TELCOM L7751-100 is a straight NPT strain relief connector designed to secure and protect cables where they pass through enclosures, panels, or junction boxes. It accepts cable diameters ranging from 2.31 to 2.44 inches and threads into a standard NPT knockout to provide a firm, vibration-resistant grip on the cable jacket. This type of hardware accessory is commonly installed by electricians and low-voltage technicians during panel builds, device enclosure work, and structured wiring installations.

This strain relief connector is suited for applications requiring a straight-entry NPT fitting with a defined cable grip range. It is appropriate for use in residential, commercial, and light industrial electrical or telecom enclosure work where cable protection and pull-out resistance at entry points are required. The connector threads into standard NPT-tapped holes or knockouts and clamps down on the cable to prevent stress from being transferred to internal terminations.

Key Features

• Straight-body NPT strain relief design for direct cable entry into enclosures
• Accepts cable jacket diameters from 2.31 to 2.44 inches
• Standard NPT thread for compatibility with common knockout and tapped-hole sizes
• Provides pull-out resistance to protect internal wiring terminations
• Sold individually as a single unit

Compatibility

Designed as an OEM-style hardware accessory for use with standard NPT enclosure knockouts and panels requiring straight strain relief fittings in the 2.31 to 2.44 inch cable diameter range.

Installation Notes

This fitting is typically installed by licensed electricians or low-voltage technicians. De-energize all circuits and follow applicable NEC guidelines before working inside any enclosure. Thread the connector into the NPT knockout until snug, route the cable through, and tighten the clamping nut to secure the cable jacket without crushing or deforming it. Do not overtighten, as excessive force can damage the cable jacket or fitting threads.
