This rectangular white skylight dome lets natural light into your RV with a 30-1/8 by 18-5/8 inch flange that seals over a standard 27 by 15-3/4 inch roof opening. Standing 5-1/2 inches tall, it offers more interior headroom than typical 4-inch domes. Moulded from impact-resistant polycarbonate, it handles hail, road vibration, and UV exposure without crazing or yellowing. Sealant is needed but sold separately.
