Frequently Asked Questions

How do I know if this weathershield fits my Dometic awning?

This weathershield is designed for 21-foot Dometic patio awnings. Measure your awning fabric length when fully extended, or check your awning's model label typically located on the roller tube or arm. If your awning measures 21 feet and uses a 6-slat weathershield design, this is the correct replacement.

Can I replace just the weathershield without removing the entire awning?

Yes, the weathershield can typically be replaced while the awning remains mounted to your RV. You'll need to fully extend the awning, remove the old weathershield from the roller tube, and slide the new one into position. The process is straightforward but may require a helper to manage the length.

What causes weathershields to deteriorate and need replacement?

Constant exposure to UV rays, extreme temperatures, and weather cycles causes vinyl weathershields to become brittle, crack, or tear over time. Individual slats may break or separate from the mounting strip. Replacing a damaged weathershield prevents moisture and debris from damaging your expensive awning fabric.

Will this black weathershield match my awning color scheme?

Black is the standard color for Dometic weathershields and provides a neutral appearance that complements most awning fabric patterns. The weathershield is only visible when the awning is retracted, wrapping around the roller tube in a low-profile design.
