- Prepare the Outlet: Ensure the wall outlet you intend to use is a standard duplex outlet and is free from obstructions.
- Attach the Shelf (Optional): If you wish to use the removable shelf, slide it into the designated slots on the top of the outlet extender until it clicks securely into place. The shelf is designed to be stable and can hold small items.
- Plug In: Align the prongs of the outlet extender with the top receptacle of your duplex wall outlet. Gently push the extender firmly into the outlet until it is flush with the wall.
- Secure with Screw: For enhanced stability, use the provided mounting screw to secure the extender to the wall outlet's center screw hole. Turn the screw clockwise until it is snug. Do not overtighten.
- Stability Rod: The extender also features a plastic prong at the back for additional stability. If this prong interferes with installation on certain outlets, it can be carefully cut off.
