The AllElectrics 2-Gang 35mm Metal Back Box is a type of electrical mounting box designed for use in residential, commercial, and industrial electrical installations. Here's an overview of its features and purposes:

• 2-Gang: This designation means the back box is designed to accommodate two electrical devices, such as double sockets, dual switches, or other similar fixtures. It has two separate compartments or spaces, allowing for the installation of two devices side by side.
• 35mm: This measurement indicates the depth of the back box. At 35mm deep, this back box provides more space compared to the standard 25mm depth. This additional depth is useful for managing more complex wiring, thicker cables, or additional connections.
• Metal: The back box is made from metal, typically steel or a similar durable material. Metal back boxes are valued for their strength and resistance to physical damage, making them suitable for a wide range of applications. They also provide better protection for electrical connections compared to plastic alternatives.
• Back Box: This component is installed into the wall cavity and serves as the mounting base for electrical devices. It helps protect the wiring and provides a stable, secure platform for attaching the devices.
• Usage: The 2-Gang 35mm Metal Back Box is used where two electrical devices need to be mounted. It is particularly useful in installations where additional depth is required for managing wiring, which can be beneficial in more complex setups or when dealing with larger cables.

In summary, the AllElectrics 2-Gang 35mm Metal Back Box is a robust and practical solution for mounting two electrical devices. Its 35mm depth allows for more space behind the devices for wiring, and its metal construction ensures durability and protection.
