Tri-Cor International was established in 1980 to manufacture automatic gate operators which were distributed through a national network of dealers. These commercial gate operators were required to move gates weighing thousands of pounds hundreds of times a day. In 2000 management discontinued manufacturing gate operators and began distributing them. The empirical knowledge gained in this demanding industry was used in the design and testing of the Private-Door.
The Private-Door was developed for executives and professionals to provide privacy. Learning of the growing markets of the physically challenged and the maturing of America, Private-Door's design was enhanced to serve these individuals.
Tri-Cor's goal is to remove the barriers that doors cause these individuals and the exorbitant cost to automate them. Private-Door is the first affordable automatic door operator that provides independence for the physically challenged, allows mature Americans to open and close doors with ease, and provides convenience for the executive and homeowner.
