F-40 48" x 48" Equipment Access Roof Hatch – Steel Curb & Aluminum Cover – Bilco 

Bilco designed the F-40 for buildings that need a simple yet functional roof hatch that allows service personnel to access the roof for installation or routine checks quickly. The single-cover customizable roof hatch has an excellent structural design that will enable it to withstand inclement and extreme weather conditions.  

Why Install F-40? 

Weathertight: Bilco designs F-40 to prevent water leakage and keep harmful chemicals and elements from infiltrating the building, which may cause extreme damage in the long run. The weather tightness of the equipment roof hatch also helps regulate the building's temperature, minimizing air leakage and temperature fluctuations.  

Customizable: The F-40 is available in different sizes and is customizable to accommodate the building's specific needs.  

Accessibility: The F-40 has a simple yet effective design that allows authorized personnel to quickly and safely access the roof. The roof hatch has compression spring operators and automatic hold-open arm features that prevent the cover from accidentally opening or closing.
