Rv Skylight Outer Dome

RV Skylight has rough hole opening of 14"x22" and flange of 17"x25", with a height of 4 inches. DOES NOT INCLUDE INNER GARNISH (must be purchased separate). High performance poly-carbonate skylights are virtually unbreakable and easy to clean.

Always use sealant (10oz tube included). Note, inners must be the exact size as the hole you are working with.
