Leviton Telcom L7543 Strain Relief Grip Nylon 0.500 in

Product Description

The LEVITON TELCOM L7543 is a nylon strain relief grip with cord seal, designed to secure and protect electrical cords at entry points in enclosures, panels, and junction boxes. The 0.500-inch cord opening accommodates standard round cord diameters and provides a compression seal that resists pull-out forces and reduces mechanical stress on wire connections. Made from nylon, the grip offers corrosion resistance and durability in both indoor and light commercial environments. Electricians and low-voltage installers use this type of fitting wherever cord management and strain protection are required at a panel or enclosure knockout.

This strain relief grip is suited for residential and light commercial electrical installations where cords or cables pass through enclosure walls, conduit knockouts, or device housings. It is typically installed in situations requiring both a mechanical grip on the cord jacket and a basic seal at the penetration point. The 0.500-inch size fits common round cord and cable configurations used in control wiring, appliance connections, and similar low-voltage or line-voltage applications.

Key Features

• Nylon construction provides corrosion resistance and long service life
• Cord seal design limits ingress at the enclosure penetration point
• 0.500-inch cord opening accommodates standard round cord diameters

• Sold individually, unit of measure is each

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 0.500-inch knockout or threaded entry points in electrical enclosures, junction boxes, and panels.

Installation Notes

Installation is performed by a licensed electrician or qualified low-voltage technician. De-energize the circuit and disconnect power before opening any enclosure or panel. Thread the strain relief into the knockout opening and tighten the locknut to the manufacturer-recommended hand-tight-plus snug method without over-torquing nylon fittings. Follow applicable NEC requirements for cord and cable support and strain relief at enclosures.
