If you have no resources or capability to complete the necessary enclosure metalwork (drilling) we may be able to offer assistance for a nominal charge. We have inventory of the Circuit Specialties and Bud Industries enclosures, either to-be-drilled or as supplied by the vendor.

Note: While Circuit Specialties has enclosures available direct, the shipping cost for unit quantities is rather expensive. The Bud Industries enclosure is occasionally available from Amazon, usually with prime free shipping.

Power transformer options range from around $15 to $45, depending upon vendor fluctuating prices. A couple examples are listed on the website, additional references upon request.
