Mounting Hardware    

The most common method of mounting toroidal transformer and inductors onto a chassis utilizes a mounting kit comprising a metal washer and two neoprene rubber washers. The single screw mounting is labor saving, and the two rubber washers, which provide cushioning and vibration proofing as well as additional electrical insulation.

Steel washers are provided with a central depression, which helps centering the transformer and keeps the bolt head from protruding above the face of the washer. They are electro zinc plated to provide some corrosion protection, but they are not intended for open outdoor applications.
