2 Pack 1/2 Inch Single Gang Outlet Box Extender (Blue)

1/2 inch depth for common wall gaps: This box extender measures 0.5 inch (13mm) in depth, ideal for compensating when finished walls are thicker than standard. Perfect for tile backsplashes, added drywall layers, or paneling that causes outlets and switches to sit recessed from the wall surface | Single gang design for standard boxes: Designed for single gang electrical boxes, this extender fits most standard outlet and switch boxes. Outer dimensions are 3.7 x 2.2 inches (93 x 57mm). Compatible with PVC, metal, and fiberglass boxes for both new work and old work installations | Fire retardant plastic construction: Made from fire retardant plastic, this extender resists warping, cracking, and high heat. The self extinguishing material adds safety for residential and commercial electrical applications. Built to last through years of use | Easy installation: No need to remove or reposition the existing electrical box. Simply align the extender over the box, insert the longer screws (mounting screws not included), and fasten your outlet or switch. Works with standard 6-32 screws used for device mounting | Completes a safe, professional finish: Bringing outlets and switches flush with the wall surface eliminates gaps and reduces risks from loose connections. The extender helps meet electrical code requirements and provides a clean, finished look that homeowners and inspectors appreciate
