Dubbll Corp.

We are a very large Canadian Importer / Distributor of Air Conditioning equipment and would like to inquire about your Disconnect Box.

Is it approved by UL, ETL, or CSA for sale in Canada and the U. S.? If so, are you currently selling it in N. America?

We have been working with a Chinese company to get a Disconnect Box approved for sale in N. America, but they have not been able to pass the necessary tests to obtain approval.

Can you please contact us as soon as possible as we are very interested in this product and want to start a business relationship with a Chinese manufacturer immediately.
