Dometic 3310420.017U 9100 Left-Hand Torsion Assembly - Black

Dometic 3310420.017U is the left-hand (LH), black torsion/spring assembly for compatible Dometic 9100 Power Patio awnings. Dometic's 2024 and 2025 parts catalogs explicitly identify the 3310420.017U torsion assembly as left-hand. This is not a right-hand assembly.

Important handedness and model check

For the standard 9100 Power Patio configuration, Dometic lists the powered motor drive separately on the opposite roller end (black motor MPN 3310423.209U). Confirm the awning's product ID, the original LH torsion number, finish and roller-tube design before ordering. Some LED-in-the-roller-tube configurations use a different LH torsion assembly, such as 3310420.112U, and are not assumed interchangeable with this part.

Spring-tension safety

Awning torsion assemblies contain hazardous stored spring energy. This replacement is not a complete roller, awning fabric or arm-hardware kit. Do not remove a tensioned assembly or its restraints without Dometic's applicable service procedure; use a qualified RV service technician.
