GEATaaT RV Skylight Outer Dome, Smoke 18"x26" Flange — UV-Resistant, Impact-Resistant Replacement

GEATaaT RV Skylight Outer Dome is a smoke-tinted, impact-resistant replacement dome designed to fit standard 14" x 22" RV skylight openings with an 18" x 26" flange.

This outer dome replaces worn or cracked skylights on travel trailers, campers, motorhomes and truck campers. Molded from UV-treated polycarbonate, the dome resists weather, sunlight and everyday impacts while restoring natural light and exterior protection. It’s supplied with the basic hardware and adhesive for straightforward installation so you can refresh your RV’s look and function quickly.

How will this skylight dome improve my RV’s interior lighting and comfort?

The smoke tint balances daylight admission and glare reduction, letting in soft ambient light without harsh direct sun. The dome’s four-inch profile provides headroom for the factory skylight assembly and keeps the interior brighter during daytime travels. UV coating reduces interior fading and helps keep soft furnishings and finishes protected.

• Smoke tint moderates brightness and reduces glare.
• UV-resistant polycarbonate minimizes sun damage over time.
• Four-inch dome height preserves headroom and airflow options.

Does this dome fit my RV and how do I confirm sizing?

Measure your existing skylight opening and flange to ensure compatibility: the dome itself measures 14" x 22" x 4" while the outer flange spans 18" x 26". It is intended for standard 14" x 22" openings commonly used in many RVs and trailers. If your opening matches those dimensions, this dome is a direct-fit replacement in most cases.

• Dome dimension: 14" x 22" x 4" for the visible skylight section.
• Flange (outer dimension): 18" x 26" to match existing mounting flanges.
• Designed for most travel trailers, campers and truck campers using standard openings.

What materials and durability features does the GEATaaT skylight offer?

The dome is made from durable polycarbonate known for impact resistance and long-term outdoor use. An integrated anti-UV coating helps block harmful rays that accelerate interior fading and brittle plastics. Built to withstand road vibration, rain and moderate hail exposure, the material offers a reliable weather barrier for seasonal and full-time RV use.

• High-impact polycarbonate resists cracking and shattering.
• Anti-UV coating protects interiors and extends dome life.
• Weather-resistant design for rain and varying temperatures.

How easy is installation and what comes with the replacement dome?

GEATaaT supplies the screws and adhesive needed for a typical replacement, and many customers complete the swap with basic hand tools. Installation steps are straightforward: remove the old dome, clean the opening, apply the supplied adhesive, position the new dome and fasten the flange. Support resources such as installation videos can help if you prefer visual guidance.
