Prevent electronic equipment with removable input power cords, such as computers and power supplies, from being plugged in and powered up with the Power Cord Plug Lockout from Accuform. This built-in, 3-pin plug connection is also known as an IEC plug. To use, turn power off and remove power cord. Insert the orange, nylon plastic lockout into the plug well in the equipment, rotate the thumbscrew to tighten, line up holes, and secure with padlock (sold separately).
