They are referring to the brackets that mounts to the slide. If you donít screw them into a solid backed surface they will pull out. Jayco mounted one of my toppers only into the fiberglass side wall. It pulled out and destroyed the awning. Good thing it was under warranty. On 2019 model eagles, they need to be mounted to the slide upper trim piece. If in doubt, have them installed by an rv dealer.
