The Dometic Awning Rail (Part# 3308286.186-B) is a genuine OEM replacement rail designed to secure your RV awning fabric to the side of your motorhome or trailer.

Frequently Asked Questions

Can I cut this rail to a shorter length if my awning is less than 16 feet?

Yes, this aluminum rail can be cut to size using a hacksaw or metal cutting blade. Measure carefully and deburr the cut edge before installation. Many RV owners order the next size up and trim to exact length for a custom fit.

Does this rail come with mounting screws or installation hardware?

No, mounting hardware is sold separately. You'll need appropriate screws for your RV sidewall material (aluminum, fiberglass, or wood substrate). Use stainless steel screws with rubber washers and sealant to prevent water intrusion.

Will this polar white rail match my existing RV trim color?

Polar white is Dometic's standard white finish and matches most RV exterior trim. However, RV manufacturers use various shades of white. If exact color match is critical, compare a sample of your existing trim before installation.

Can I install this rail myself or do I need professional help?

Many experienced RV owners install awning rails themselves with basic tools. You'll need a drill, level, sealant, and helper to hold the rail during installation. Proper sealing is critical to prevent water damage. If you're not comfortable working on your RV exterior, professional installation is recommended.
