D50 48" x 48" Equipment Access Roof Hatch – Aluminum – Double Leaf - Bilco  

The D50 Equipment Access Roof Hatch – Aluminum – Double Leaf has an excellent strength-to-weight ratio that reduces the building's stress and an undeniable insulation feature that can help you lower your energy bill in the long run. In addition, the roof hatch's primary material makes it easy to maintain, reducing the number of scheduled maintenance and repair visits for years and saving you more from service fees and other charges.   

Why Install the D50 Equipment Access Roof Hatch?  

Material: The lightweight yet durable aluminum is the roof hatch's primary selling point as it reduces the roof's pressure and strain for holding an additional load, making the D50 one of the construction industries' favorite products.   

Longevity: The aluminum's rust and corrosion-resistant features allow it to last longer than ten (10) years, whether or not the roof hatch is in coastal areas that can highly contribute to the materials' corrosion.   

Installation: Aluminum is lighter than other metals, making it ideal for equipment roof hatches that need transportation services. A thorough installation process allows the installation personnel to quickly and efficiently set up the D50.
