Overview

The **Woodhead Watertite® Plug with Locking Blade (SKU: 28W49)** is a NEMA L7-30 industrial-grade connector designed for 277V, 2-pole plus ground (2P+G) applications. Built with a **F4 (1") cord grip body**, this plug features nickel-plated brass blades and contacts, a NEo-TEX® Paracril OZO rubber grommet, and stainless steel face screws for corrosion resistance. The locking blade mechanism prevents accidental disconnections in high-vibration environments, making it ideal for manufacturing, construction, and outdoor installations. Certified to **NEMA 1, 3, 4, 4X, 5, 6, 6P, 12** and **IP55–IP67** ratings, the 28W49 withstands moisture, dust, chemicals, and high-pressure washdowns up to 1000psi. Operating from **-40°C to 75°C**, it includes a three-piece strain relief system to protect cables from pull-out and damage. The transparent wiring guide ensures proper strand alignment, while color-coded ¼" terminal screws (tri-drive compatible) simplify installation. Trusted by industries like oil and gas, mining, and agriculture, this UL-listed (E10176) and CSA-certified (LR6837) plug meets NSF/ANSI/3-A 14159-1 standards for food-grade and sanitary applications.
