The ATS electric retractable sill plates on the Cadillac Escalade Long are installed in the same place as the fixed ones.  On the Cadillac Escalade we have sills with and without undercolor. The sills on this vehicle have the ability to be controlled from the OEM key fob when the vehicle is opened. We talk about this in these videos. The warranty on our retractable sills is 2 years. We also perform maintenance of the sills.
