Dometic™ A&E 8952012.400UL RV 9100 Power Awning Arm - Standard - Black

Restore or replace a worn awning arm with the Dometic A&E 9100/9200 Power Awning Arm (Part #8952012.400UL / 9108853270) in black. Standard-style arm built specifically for Dometic 9100/9200 Power Awnings, with a top wire exit configuration — the arm geometry used on the majority of RVs equipped with Dometic awning hardware.

⚠️ TOP WIRE EXIT — Critical Fitment Detail

This arm is specifically the TOP WIRE EXIT variant. Verify your existing installation's wire exit direction before ordering:

Prefer Bottom Wire Exit at a Lower Price?

See the Dometic 3312487.006U Bottom Wire Exit Standard Pitch Arm. Same standard-pitch geometry with a 13-1/4" drop, but with bottom wire exit configuration.

The wire exit direction is fixed on the arm architecture — you can't reroute wiring to match a mismatched arm. Match your existing setup exactly.

The Workhorse of Your Awning System

Extension arms are a crucial part of any RV awning — they mount to your sidewall and extend outward to support the fabric roller tube assembly, providing the tension that keeps the fabric taut and stable when deployed. Without a properly functioning arm, your awning sags, flaps in the breeze, and can fail prematurely. This is a genuine Dometic OEM replacement to keep your 9100/9200 system working the way it was designed to.

Gas Strut Support

The arm includes a gas strut that creates and maintains tension on the awning when extended, helping it stay in place even in breezy conditions. Beyond just tension, the strut helps distribute the weight of the awning fabric and reduces stress on the extension arms and the RV sidewall — extending the life of your whole setup.

Adjustable Pitch for Sun and Rain

The adjustable pitch feature lets you angle the awning for better sun protection (especially useful in early morning or late afternoon when the sun is low) and helps prevent rainwater from pooling on the fabric. To adjust, loosen the knob on the adjustable arm, move it up or down to your preferred angle, and retighten — simple and tool-free.

Standard Style Geometry

This is the standard-style arm widely used on modern RVs, with standard lengths for both the back and front channels and a standard pivot point that produces a 13-1/4" drop of the awning when extended. If your setup uses a shallower deployment angle instead, see the Dometic 9100 Power Awning Arm – Reduced Pitch (8952013.400UL).

Compatibility

This arm is compatible with Dometic 9100/9200 Series Fabric Roller Tube Assemblies, as well as awning tubes from the 915, 917, and 910 Series.

Replacing the Fabric Too?

If your awning fabric is also weathered, faded, or torn, we carry matching Onyx Fade replacements for the 9100 system in two underside options:

• 9100 Onyx Fade fabric replacement (black on both sides)
• 9100 Onyx Fade fabric replacement with polar white underside

Important Notes About Hardware Finish & Construction

Dometic uses two different painter suppliers, which means hardware finish may appear glossy, matte, or even a mix of both within the same hardware set (left and right arm). Dometic does not consider this variation a defect and does not offer exchanges or alternatives based on finish appearance.

The hardware back channel may have a slight bow due to the manufacturing process. This is not a defect — upon installation, the hardware will sit flat against the RV. The awning arm is intentionally engineered to be lightweight and to rely on the strength of your RV's sidewall for support.
