Overview

The Woodhead Safeway® Flanged Inlet (SKU 2881MB) is a 30A, 3-phase, 208V locking blade inlet designed for secure industrial power connections. Engineered with a NEMA L21-30 configuration, it supports 4-pole/5-wire systems, including neutral and ground conductors, for balanced 3-phase power distribution. The flanged design ensures stable mounting in high-vibration environments like factory floors and construction sites, while the integrated locking blade mechanism prevents accidental disconnections, ensuring continuous power to critical equipment. Constructed with a NEo-TEX® Paracril OZO rubber body, this inlet delivers superior performance in abrasion, chemical exposure, and extreme temperatures. Key features include color-coded ¼" tri-drive terminal screws for easy wiring, floating blade construction for self-alignment and reduced wear, and a transparent wiring guide to verify proper wire strand placement. The two-piece cord-clamp strain relief with tri-drive screws secures cables firmly, while stainless steel speed screws ensure long-term reliability.
