Transformers are supplied with one metal washer and two rubber pads, however other mounting options are available:

Enclosures

The above transformers can be ordered mounted inside a NEMA enclosure with or without fuse, receptacle and line cord with plug.

Vertical Mounting

When vertical mounting of the transformer is required we recommend using our Omega or L- brackets. Learn more at our Mounting and Hardware section.

Caution - If you choose to apply your own mounting solution, remember that it is important that our transformer be mounted in such a way that the mounting screw and the metal chassis will not form a closed loop through the center and thereby create a shorted turn on the transformer.
