The Icon RV Skylight is a high quality replacement skylight dome. A skylight can enhance the ambience of a room and help maintain a more comfortable, consistent indoor climate without wasting energy. It is made from durable, impact resistant poly-carbonate. It has a 2" flange that allows for an easy and leak free seal to the roof of your RV. The translucent white dome provides more privacy and a diffused light. Icon Skylight Sealant (sold separately) is recommended for installation.
