OEM right-hand torsion assembly for Dometic 9100 Series Power Awnings. 12V DC, black finish. Replaces worn or seized awning drive motors.
The Dometic 3310423.209U is the OEM right-hand torsion assembly (power drive assembly) engineered specifically for the Dometic 9100 Series Power Awning.

Runs directly off your RV's 12-volt DC system — no converter or additional wiring required
Precision-engineered replacement that installs in the exact same location as the factory unit
Constructed to withstand harsh outdoor conditions including heat, moisture, and road vibration
Riveted installation requires only basic hand tools and a rivet gun — no special equipment needed
