The E-50TB Roof Access Hatch is ideal for applications requiring access slightly larger than the typical 915mm x 760mm opening. The E-50TB is commonly used to provide personnel access onto the roof and for moving small pieces of equipment to and from the roof area.
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 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 with corrosion-resistant materials 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.
