Frequently Asked Questions
Q: How do I know if my rafter knob assembly needs replacement?
A: If your awning rafter arms slip or don't stay in position when extended, or if the knob spins freely without tightening, it's time to replace the assembly. Worn knobs compromise awning stability and safety.
Q: Is this compatible with all Dometic manual awnings?
A: This part fits Dometic manual awning systems that use 0.75" stud rafter assemblies. Check your awning documentation or contact our expert support team to confirm compatibility with your specific model.
Q: Do I need to remove the entire awning to replace this knob?
A: No. You can typically access and replace the rafter knob assembly without removing the awning from your RV. The exact procedure depends on your awning model—our support team can walk you through it.
