A designed invented nearly a hundred years ago, twist lock receptacles are a classic device used in wiring to provide extra safety and reliability to many appliances. From light fixtures to equipment and hardware, having a secure and stable connection to power is essential to ensuring proper function, as well as preventing potential hazards and faults. They work pretty much exactly how they sound - once a plug is inserted into the socket, it twists and interlocks the blades with the receptacle. This coupling makes the connection more reliable, providing extra security in tougher environments. Perfect for commercial and industrial applications, they will allow you to work with confidence, knowing your hardware or light fixtures will remain steady and perform when you need them all day long.
