L50 30" x 96" Service Stair Access Roof Hatch – Aluminum – Bilco 

The L50 Service Stair Access Roof Hatch – Aluminum is perfect for roof installation due to its excellent strength-to-weight ratio. It can effectively withstand pressure up to 40 psf (195 kg/m2) live load without putting extra stress on the roof. It provides additional safety measures for the people inside the building accessing it through the service stairs. 

Why Install L50?  

Durability: L50's primary material is aluminum, known to resist weather and corrosion due to its ability to form a protective layer when exposed to air. It can also hold a relatively significant amount of stress. These features make L50 best installed in commercial and industrial buildings located in coastal areas or prone to harsh weather conditions.  

Accessibility: The 11 gauge (2.3 mm) aluminum weight and the automatic arms lock provide quick and easy access to service and authorized personnel when moving equipment to and from the roof.  

Safety: The roof hatch's 3/8" (9 mm) sturdy and secure pintle hinges and the two-point latch system help prevent intruders from getting inside the building. In addition, the hinges aid authorized personnel in safely and smoothly opening and closing the cover, which mitigates the danger of injury.
