About the AmeriGlide Express Dumbwaiter: The AmeriGlide Express was made to meet two goals: it should be easier to install than the alternatives and it should be economical to own. With those goals in mind, the AmeriGlide Express uses a special drive train system where the entire drive is preinstalled on the underside of the car. In addition, the car chassis system is preinstalled on a section of the track. All of this means that the installation process has been greatly simplified, cutting up to a full day of installation time. This simple design also gives you long-term reliability and a lower overall cost. AmeriGlide backs this up with a 2-year parts warranty and a 5-year drive train warranty.
