About Product Overview

This Leviton locking plug is built for connections that can't afford to work loose. The twist-lock NEMA L14-20P design seats securely and stays put even with vibration or movement nearby, which is exactly why industrial and commercial crews reach for this style over a standard straight-blade plug. Grounding 3-pole, 4-wire construction handles 125/250V loads, and the nylon housing shrugs off the bumps and drops that come with daily use on job sites or in shops.

  • NEMA L14-20P locking plug configuration
  • 3 pole, 4 wire grounding design
  • 125/250 volt rating
  • Industrial-grade nylon housing
  • Accepts wire range 18-10 AWG
  • Black/white housing, sold individually

Go ahead. Check.

You're going to open the other tab. Everybody does. We'd rather say so than pretend otherwise — so open it. We'll wait.

When you're over there, check four things before you click buy.

01

Who's actually selling it

The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.

02

Whether the warranty survives

Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Leviton. A third-party marketplace seller usually isn't.

03

Where the box came from

Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.

04

Who you call when it breaks

Ours is a phone number with a person behind it who has held this product. M–F, 6 AM – 5 PM Pacific. (866) 469-8556

We're not always the cheapest.

Sometimes you'll find it for less. Sometimes you'll find it for more. On a lot of brands the number is identical everywhere it's sold legitimately — the manufacturer sets a minimum advertised price and every authorized dealer holds it. When a price sits well under that, it's worth asking why before it's worth celebrating.

Shop Local · Support Independent

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
