Dometic 9100/9200 Awning Arm | 3312487.337U | Reduced | Bottom Wire

Restore or replace a worn awning arm with the Dometic A&E 3312487.337U RV Power Awning Right Arm — Reduced Pitch, BOTTOM WIRE EXIT (Black). Right-side awning arm hardware for Dometic 9100 or 9200 Power Awnings — the reduced-pitch geometry version at a lower price point than the top-wire-exit alternative.

⚠️ BOTTOM WIRE EXIT — Verify Match with Your Installation

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

• Wire exits from the BOTTOM of the arm → this 3312487.337U is the correct match (this listing)
• Wire exits from the TOP of the arm → order the Dometic 8952013.400UL Top Wire Exit Reduced Pitch Arm instead

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.

Reduced Pitch Style

The reduced-pitch awning arms are less common but are still used by some RV manufacturers. They come with standard lengths for both the back channel and front channel — the difference is that the pivot point is raised, resulting in a 2" drop of the awning when extended (vs the steeper standard-pitch drop).

Useful for:

• Taller RVs
• Mounting positions where standard pitch would put the awning too low
• Installations designed with reduced-pitch geometry from the factory

Compatibility

Compatible with:

• 8952003.400 Awning Hardware Systems
• 8962003.400 Awning Hardware Systems
• Dometic 9100 Power Awnings
• Dometic 9200 Power Awnings

The Workhorse of Your Awning System

The extension arm is a crucial component of the awning system:

• Mounts to your RV sidewall and extends outward
• Supports the fabric roller tube assembly
• Provides tension to keep fabric taut and stable
• Supports fabric weight — prevents sagging and flapping in the wind
• Provides a stable base for shade and weather protection

Gas Strut Support

Equipped with a gas strut that creates tension on the awning when extended — keeping it stable even in breezy conditions. The strut also distributes fabric weight and reduces stress on the arm and your RV's sidewall, extending overall service life.

Adjustable Pitch

The arm includes adjustable pitch for fine-tuning the angle for sun protection or rainwater runoff:

• Loosen the knob on the adjustable arm
• Move the arm up or down to change the awning angle
• Tighten the knob to secure in place

Replacing the Fabric Too?

If your awning fabric is also worn, faded, or torn, we carry matching Onyx Fade fabric 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.
