EXCELFU RV Awning Mounting Brackets — Dometic SunChaser Compatible, 2-Pack Heavy-Duty Lower Arm

This EXCELFU 2-pack mounting bracket replaces the lower awning arm bracket on Dometic SunChaser-style RV awnings, providing a secure, heavy-duty bottom mount for your awning legs.

When an RV awning bracket becomes worn, bent, or corroded it can prevent the awning leg from seating properly and compromise stability. These EXCELFU replacement brackets are built for exterior use and designed to match the footprint and hole spacing of the common Dometic SunChaser lower arm, so you can restore safe clipping and support without a full awning assembly replacement. Review the dimensions before ordering to ensure a correct fit.

Will these brackets fit my RV awning?

The brackets match the standard replacement footprint for many Dometic SunChaser-style lower awning arms, including part number 3104653.005. However, correct fit depends on mounting hole spacing and base size. Measure your old bracket to confirm compatibility before purchase.

• Base dimensions: 3-1/2" x 2" (88.9mm x 50.8mm)
• Center-to-center hole distance: 2-9/16" (65mm)
• Intended for bolt or bottom wall-mount installation
• Designed as a replacement for worn or damaged lower awning arm brackets

How durable are these replacement brackets outdoors?

These brackets are fabricated from heavy-duty metal and rated for outdoor use to resist the elements in normal RV conditions. Proper installation and periodic inspection will extend service life, especially in coastal or high-corrosion environments.

• Heavy-duty metal construction for strength and longevity
• Engineered to support the awning leg and maintain clip engagement
• Intended for exterior use; check and treat mounting hardware to prevent rust
• Sold as a 2-pack so you can replace both sides at once

What installation method is required and what hardware is included?

The bracket supports bolt-through and bottom wall-mount installations and is designed to accept the awning leg clip easily. Mounting hardware is not included, so use appropriate bolts, screws, and washers rated for exterior use and load capacity of your awning.

• Installation: bolt or bottom wall-mount; choose fasteners suitable for your RV material
• Mounting hardware not included—select stainless or corrosion-resistant fasteners
• Follow manufacturer torque and spacing recommendations for secure attachment
• Replace both sides when one shows wear to keep awning alignment correct

What should I check before buying these replacement brackets?

Confirm the bracket footprint and hole spacing match your existing mount, and inspect surrounding awning components for additional wear. Choosing correct fasteners and ensuring the mounting surface is structurally sound are important for long-term performance.

• Compare your old bracket to 3-1/2" x 2" base size and 2-9/16" (65mm) hole spacing
• Check the awning arm and clip for wear—replace worn components together
• Use corrosion-resistant fasteners and seal penetrations to prevent water intrusion
• Consider professional help if mounting surface is weakened or damaged

Who is this for: RV owners, technicians, and DIYers who need a reliable replacement for a worn or damaged lower awning arm bracket on Dometic SunChaser-style awnings. This EXCELFU 2-pack is ideal for people who want a heavy-duty, direct-fit bottom-mount solution and are comfortable selecting appropriate exterior-grade fasteners and following basic installation steps. If you’re replacing one damaged bracket or doing a coordinated maintenance refresh of both lower mounts, these brackets restore secure clip engagement and structural support when properly matched and installed.
