Leviton Telcom L7703-100 Strain Relief 3/8 Npt

Product Description

The LEVITON TELCOM L7703-100 is a straight male strain relief connector designed for 3/8 inch NPT fittings with a cord grip range of 0.31 to 0.38 inches. Strain reliefs protect cable and conduit entry points by securing the cable jacket and preventing tension, vibration, or pull-out forces from reaching internal terminations. This fitting is sold individually and is appropriate for use in electrical enclosures, junction boxes, and panel installations wherever cable management and mechanical protection are required at a conduit entry point.

This strain relief is suited for light commercial and residential electrical applications where a 3/8 inch NPT threaded entry is present. Electricians and low-voltage installers use straight male strain reliefs at enclosure knockouts to secure power, control, or communication cables passing through metal or plastic boxes. The 0.31 to 0.38 inch grip range accommodates a narrow range of jacketed cable diameters, so confirming cable OD before installation is essential.

Key Features

• 3/8 inch NPT male thread for standard knockout or conduit entries
• Cord grip range of 0.31 to 0.38 inches accommodates small-diameter jacketed cables
• Straight body orientation for direct in-line cable entry
• Single-unit quantity for targeted replacement or individual installation use

Compatibility

Designed as a standard-thread replacement or new-install strain relief for electrical enclosures, junction boxes, and control panels with 3/8 inch NPT threaded knockouts or fittings.

Installation Notes

Installation is typically performed by a licensed electrician or low-voltage technician. De-energize the enclosure or panel completely before threading this fitting into the knockout. Hand-tighten first, then use an appropriate wrench to seat the NPT threads without over-torquing the fitting body. Verify that the cable jacket OD falls within the 0.31 to 0.38 inch grip range before tightening the strain relief clamp, as clamping outside this range may not provide adequate mechanical retention.
