The Dometic LED awning fabric is for replacing worn, torn, faded, or weather-damaged fabric without guessing at the part number. This OEM Dometic replacement is the Onyx fabric version for a nominal 21' awning and uses Polar White Vinyl Weathershield. Match SKU R3310524NR.421L and your awning's nominal size before ordering; awning fabric nominal size is not the same thing as the installed fabric's exact cut length.

Why Choose This Onyx Dometic Awning Fabric?

This Dometic Onyx 21' vinyl LED replacement awning fabric with Polar White Vinyl Weathershield is a cleaner path than trying to match generic fabric by appearance. The key buying checks are the Dometic part number, nominal awning length, fabric color, and weathershield color. When those match, you can replace the worn fabric while keeping the rest of the awning setup you already have.

For this SKU, Shopify/Dometic data in this pass verifies the nominal awning size, color, weathershield, family, and part number. The exact cut fabric length can differ from the nominal size; confirm against the Dometic part number on your existing awning paperwork or label.
