Bilco’s Type J-AL aluminum access doors provide access to underground areas, including water and wastewater treatment facilities, pump stations and public utilities. Available in a single- or double-leaf design and reinforced for 300 PSF or H20 loading conditions, the channel frame design and built-in drain coupling allow the doors to be used in applications where water penetration into the opening is a concern. The doors have standard stainless steel hardware, which enhance the corrosion-resistance of the product and make it well-suited for corrosive environments.
