The Dometic 3108346.020 is a 20-foot aluminum roller tube designed for Dometic and A&E brand RV awnings. This is the main tube that your awning fabric wraps around, and it's a critical replacement part when your original tube is bent, dented, or damaged. If your awning won't retract smoothly or the fabric bunches unevenly, a damaged roller tube is often the culprit.

Frequently Asked Questions

Q: How do I know if I need to replace my awning roller tube?
A: Common signs include visible dents or bends in the tube, awning fabric that won't roll evenly, difficulty retracting the awning, or fabric that sags on one side. If the tube is bent from wind damage or an impact, replacement is necessary for safe operation.

Q: Can I reuse my existing awning fabric with this new roller tube?
A: Yes, if your fabric is in good condition, you can transfer it to the new roller tube. You'll need to carefully remove the fabric from the old tube and reinstall it on the new one, ensuring proper tension and alignment.

Q: Does this tube come with end caps and hardware?
A: This is the roller tube only. You'll need to transfer your existing end caps, torsion assembly, and mounting hardware from your old tube. If those components are also damaged, they should be ordered separately.

Q: Will this fit both manual and electric awnings?
A: Yes, this roller tube works with both manual and electric Dometic/A&E awning systems. The tube itself is the same; the difference is in the end cap assemblies and motor mounts, which you'll transfer from your existing setup.
