STjERN Corporation, Inc. was formed in late 2005 after its founders discovered that their protection product testing provided amazing results. We are now manufacturing and shipping "defendadoor" door protectors and "defendatrack" track protectors across the United States and abroad.

The inventor, Edward J. Stern Jr. worked in the Pacific Northwest, and provided many years of consulting and design for several types of processing plants and construction projects prior to starting the Stjern Corporation.

Invention Conception

Over the years, I have witnessed somewhat of a dilemma throughout the shipping and warehousing industry. This often occurs between managers wanting top speed production without damage and expense to their shipping doors, and employees striving to meet that productivity, while at the same time, often making costly mistakes. After consulting with and interviewing both forklift operators and facilities managers, I was able to gain a better perspective of the problem. Subsequently, their requests for some sort of solution was the basis for my development of the "defendadoor" and "defendatrack" that are currently on the market today.

The "defendadoor" door protectors and the "defendatrack" track protectors are made from the highest quality materials available and are manufactured in the United States. I feel that our devices provide the best protection for overhead doors today, and after you have installed any of them you don't need to do anything special to make them work; take my word for it. It is our hope that these protection devices will exceed all your expectations and deliver many years of distinguishable savings toward your yearly maintenance expense.
