This industrial Twist-Lock® flush receptacle provides a locking connection for three-phase equipment in indoor dry work areas. Wire-restraint recesses help reduce terminal loosening, while voltage colour coding helps installers match compatible devices. Its all-brass mounting and grounding system offers a lower-resistance ground path and greater corrosion resistance than steel mounting systems.
