Curb Option - Modification for Metal Roofs

Base flanges of all Bilco roof hatches and smoke vents can be fabricated with built-in configurations for most brands of metal building roof panels. This option offers simplified installation, and includes a built-in self-drainage feature that eliminates water accumulation on the up-slope side.
