This genuine Dometic replacement part is compatible with Dometic 9100 Series power awnings, including the WeatherPro Power Awning and 9100 Sport models. The assembly installs on the left side of the awning and serves as a direct replacement for worn, damaged, or broken torsion assemblies.

Important Safety Note: Installation requires careful handling of the tensioned spring mechanism. The rapid casting spin-off can occur if not properly controlled during installation. Do not remove the cotter pin in the end cap until the top casting is securely fastened to the mounting hardware. Professional installation is recommended for those unfamiliar with awning spring tension systems.
