A metal washer and rubber pads provide the most economical way of mounting the transformer horizontally and is adequate for transformers under 600 VA, provided the transformer is not installed in a product that receives rough handling.  Above 600 VA, epoxy potted center is standard mounting method.  Prices include mounting hardware, either a steel washer and two rubber pads or as shown for larger sizes, an epoxy potted center with one or two drilled mounting holes.

Optional Mounting Hardware

For a nominal cost you can order smaller transformers with epoxy potting, either with drilled hole or threaded inserts. The potting has a recessed top to accommodate screw head. Flat bottom is a standard feature.

The L-Bracket
An L-shaped steel bracket is an economical solution for vertical mounting. A metal washer and two rubber pads are furnished with each L-bracket. Larger transformers will have an epoxy potted center.
