Frequently Asked Questions

Q: How do I know if my rafter arm is damaged and needs replacement?
A: Signs include visible bending or warping, difficulty extending or retracting the awning, creaking or grinding sounds during operation, or the awning not sitting level when fully extended. If the arm is visibly bent or the awning sags to one side, replacement is recommended.

Q: Will this 74-inch arm fit my Dometic awning?
A: The 74-inch length is standard for most Dometic awning systems on motorhomes and travel trailers. Verify your current arm length before ordering. If you're unsure, check your awning model number or contact our expert support team.

Q: Can I install this myself, or do I need professional help?
A: Most RV owners can install this arm with basic tools. The assembly bolts securely to your awning head. Refer to your Dometic awning manual for step-by-step instructions, or our support team can walk you through the process.
