The Leviton L7504-100 is a dust-tight cord grip fitting engineered with a 3/4" NPT threaded connection, designed to secure and seal flexible cordage as it passes through an enclosure wall, panel, or junction box. Built to maintain a dust-tight seal at the point of cord entry, this fitting is a practical solution for electricians and facility maintenance teams who need reliable strain relief combined with environmental protection against airborne particulate. The 3/4" NPT thread size allows for straightforward installation into standard threaded knockouts and enclosure openings, making it a common choice across industrial, commercial, and light manufacturing electrical installations where cord management and ingress protection are both priorities.

Leviton L7504-100 – Frequently Asked Questions

1) Will the Leviton L7504-100 cord grip thread into a 3/4 inch knockout on my enclosure?
The L7504-100 has a 3/4 inch NPT male thread, so it threads directly into a tapped 3/4 inch enclosure opening or hub with no adapter. A plain punched knockout is not threaded, so on sheet metal boxes you either need a tapped hub or a locknut arrangement to secure it. Trade size 3/4 is the only size this model comes in.
2) Is the Leviton L7504-100 suitable for outdoor or wet locations?
It is a dust-tight fitting, built to block airborne particulate at the cord entry. That is a different rating from watertight or raintight, so for a washdown area, an outdoor panel, or anywhere liquid gets sprayed at the enclosure, specify a liquid-tight or watertight cord connector instead. Use the L7504-100 where dust, not water, is the problem.
3) What does a dust-tight cord grip actually do that a plain strain relief bushing does not?
Two jobs at once. The L7504-100 clamps the cord so pulling on it does not transfer stress to the conductors and terminations inside, and it seals around the cord jacket at the entry point to keep airborne particulate out of the enclosure. A plain bushing only protects the jacket from the metal edge. If you are in a woodshop, grain handling area, cement plant, or any dusty manufacturing space, the sealing function is the reason to spec a dust-tight grip.
4) Do I need a sealing locknut or extra hardware to install the Leviton L7504-100?
Into a tapped 3/4 inch NPT hub, the fitting threads straight in on its own, which is the point of the NPT connection. On an untapped sheet metal opening you supply the locknut, and in a dusty space a sealing locknut or gasket is worth adding so the seal at the cord does not get undone by a leaky hub. The grip itself handles the seal around the cord jacket.
5) How do I order the Leviton 3/4 inch dust-tight cord grip? Is there more than one version?
One configuration: Leviton model L7504-100, the 3/4 inch NPT dust-tight cord grip. No finish, length, or handing choices to specify, so the part number alone is the order. For other trade sizes you would be moving to a different Leviton cord grip model.
6) Where on a job does a 3/4 inch NPT cord grip like this get used?
Anywhere flexible cordage has to pass through an enclosure wall and stay put: junction boxes, industrial and commercial panels, machinery and equipment wiring, and panel retrofits where loose cord entry is the existing problem. Maintenance crews use them to clean up cords that were run through bare knockouts, which both seals the opening and takes the pull off the terminals.
