The Arlington BE4 Box Extender is designed to support the wiring device where the box is set back from the wall surface. This extender can extend the box by up to one and a half inches, accommodating various installation needs. Made of durable non-conductive plastic, the box extender is suitable for both metal and non-metallic electrical boxes and features a two-hour fire rating.
This product is essential for installations where electrical boxes are recessed in walls, ensuring that wiring devices are flush with the wall surface. It helps prevent arcing between the box and device screws while providing a secure and level support for switches and receptacles.
