Clear Acrylic Dome (bronze is shown in picture); Inside Curb Rough Opening-22.5" x 34.5"; Double Dome; Aluminum Retainer Cap Available in Brown, Black, White or Mill Finish; *****PLEASE SPECIFY RETAINER CAP COLOR IN COMMENTS AREA WHEN CHECKING OUT; IF NO COLOR IS SPECIFY, MILL FINISH WILL BE ORDERED***** MSF (Metal Self Flashing Skylights) – Our uniquely designed Metal Self Flashing skylight is mounted directly to the roof deck of the vehicle, which makes the skylight easy to install. Likewise, our skylight is easy to repair. The acrylic dome can be quickly replaced by simply removing the aluminum cap and exterior skin. All the while, the roof of the vehicle stays intact to prevent damages. Dayliter Metal Self Flashing skylights have a patented No-Leak Skin which guarantees that no amount of water will enter the interior of the vehicle. The outer skin is designed to direct water flow away from the skylight and towards the roof, ensuring a dry interior. The Safety Water Stop in the MSF skylight is an integral component for any vehicular skylight. It prevents water from traveling up into the skylight as the vehicle is in motion.
