About :

The extension ring typically measures 1-7/8 inches in depth. This dimension is crucial for ensuring that it fits properly with existing electrical boxes and provides enough space for additional wiring or components. These extension rings are often made from durable materials like galvanized steel or plastic. The choice of material affects the ring's durability, grounding capabilities, and suitability for different environments. Designed to be compatible with standard electrical boxes, these extension rings are used to extend the capacity of the box. This is useful when additional wiring or larger devices need to be accommodated. It's important that these rings meet relevant safety standards and building codes. They should be certified for their intended use and comply with standards set by organizations like the National Electrical Manufacturers Association (NEMA).
