The 8952002.400UL number comes back to a Dometic power awning arm. The Replacement Support Arm Assembly for Lippert Edge 58" Awning LC77VR would not be the correct replacement.
We do not carry a direct replacement for your 8952002.400UL because we do not carry Dometic awnings. The closest that we would have is the Solera Smart Arm 12V Power RV Awning Conversion Kit # LC759516 which works with Dometic awnings. view full answer...
