QUAD 4000 Info DEDICATED TO QUALITY Quad Systems LLC’s primary motivation is to provide a high-quality product that simplifies our customer’s lives. Our customer is the installer who wants a product that is easy to install. Our customer is the distributor that wants to carry only one type of operator in his inventory. Our customer is the individual living with a disability whose life is made easier by having a door open automatically for him. We are in the business of opening doors. We started as a production machine shop in 2003 in Corpus Christi, Texas. Sometime later, we acquired an existing door operator manufacturing company that had a 14-year history in the automatic swing door industry. With the addition of this low energy gearbox company to our family, Quad Systems was propelled into the swing door wholesale business.
