GEATaaT RV Skylight Outer Dome 18"x26" OD Clear – UV‑Coated Polycarbonate, Fits 14"x22" Openings

If your RV skylight dome is yellowed, cracked, or leaking, replacing it restores daylight, visibility, and weather resistance while refreshing your vehicle's appearance. This outer dome measures 18" x 26" for the outer flange and covers a 14" x 22" interior opening, giving a 4" dome height that combines strength with generous interior headroom for light. Constructed from impact-resistant polycarbonate with an anti-UV surface, the dome resists sun damage and handles varied road and campsite conditions.

Will this dome fit my existing 14" x 22" skylight opening?

Yes — the GEATaaT outer dome is built to work with standard 14" x 22" skylight frames. Check the interior frame dimensions and compare flange measurements before ordering to ensure compatibility.

• Outer flange: 18" x 26" to overlap common roof cutouts
• Dome size: 14" x 22" x 4" height for interior clearance
• Designed to replace standard model SL1422C-style domes
• Works with most RV, camper, and travel trailer roof openings

How durable and weather-resistant is this skylight dome?

The dome is molded from high-quality polycarbonate, a material known for impact strength and durability under road vibration and weather exposure. Its built-in UV coating helps slow yellowing and maintain clarity over time.

• Polycarbonate construction for high impact resistance
• Anti-UV coating reduces sun-related discoloration
• Seals properly when installed using included glue and screws
• Suitable for varied climates — rain, sun, and travel wear

How simple is installation and what comes in the box?

Installation is straightforward for most DIYers: the package includes the dome plus screws and adhesive needed to secure the outer flange. Many users follow step-by-step video guides for a clean, watertight fit.

• Includes screws and glue required for mounting
• Fits on top of existing skylight frames — no roof re-cut required
• Typical install tools: screwdriver, sealant applicator, cleaning supplies
• Online tutorials available to walk through removal and replacement

What maintenance does the dome require to stay clear and sealed?

Routine cleaning and periodic checks of the sealant help prolong clarity and prevent leaks. Use mild soap and a soft cloth; avoid abrasive cleaners that can damage the UV coating.

• Clean with non-abrasive soap and soft cloth to preserve coating
• Inspect sealant seams after heavy travel and reapply if needed
• Avoid solvent-based cleaners that can cloud polycarbonate
• Address chips or cracks promptly to maintain weather protection
