The CS-50TB Roof Access Hatch is ideal for installations where frequent access to the roof area is required. At 760mm x 1500mm, the CS-50TB allows easier movement of maintenance personnel, tools and equipment to and from the roof (Patented).
BILCO Roof Access Hatches feature a thermally broken frame and cover design that minimizes heat transfer between interior and exterior metal surfaces. The result is a product that resists harmful condensation and provides superior energy efficiency. Products are tested and approved to BS EN standards for weathertightness, sound rating, and security.
Thermally broken cover and frame design provide superior thermal performance.
Engineered with compression spring operators to provide smooth, easy, one-hand operation, regardless of size. BILCO Roof Access Hatches meet the requirements of Manual Handling Regulations.
Automatic hold-open arm locks the cover in the open position to ensure safe egress. Grip handle allows for easy, one-hand release and closing.
Overlapping cover design, fully welded corners on cover and curb, closed-cell EPDM rubber gasket, and fully insulated cover and curb ensure weathertightness and energy efficiency.
Constructed from aluminium to provide many years of trouble-free, dependable service.
Heavy gauge construction and positive latching mechanism maintain building security.
Curb features the Bil-Clip® Flashing System, an innovative method to quickly and easily secure single-ply roofing material to BILCO roof products.
