After 20 years, RH Designs proprietor Richard Ross has retired, and as a result SDS have taken over the manufacture and sale of RH Designs products. This web site will remain as a source of reference and technical support but all ordering links will be directed to the SDS web site where you will be able to complete your purchase. More information is available on the About and Ordering pages on this site.
Thanks for visiting RH Designs - Dr Richard Ross, proprietor
