Hello Erasto - Custom Power Cord has been out of business for several years now, and never did have a website when they were in operation. For your RSA Haley, I would try and get hold of a Synergistic Research AC MasterCoupler (Active) as a very good input cord for this unit. You should be able to find several in the used cable market for a good price.
