Why Should You Use the 48" x 48" ADC-D-20?
- Effortless Rooftop Access: The ADC-D-20 features interior and exterior turn handles for easy opening from any side, regardless of whether you're on the roof or inside the building. Powerful compression springs with automatic locking arms ensure smooth operation and secure positioning when accessing the rooftop.
- Spacious Work Area: The D-20's large double-leaf design provides ample room for maneuvering and equipment access during maintenance or inspection.
- Simplified Installation: The D-20 boasts a 3-½" mounting flange with pre-drilled holes, facilitating a streamlined and secure attachment to your roof decks. This feature minimizes installation time and ensures a proper fit.
- Durable Weather Protection: Permanently adhered EPDM rubber gaskets create a watertight seal, keeping rain, snow, and other elements out of your building and protecting your valuables. Additionally, the D-20's corrosion-resistant construction ensures it can withstand harsh weather conditions year after year.
- Enhanced Structural Strength: The D-20 can support live loads of up to 40 lbs./sq. ft., offering significant load-bearing capacity for your roof. It can handle the weight of equipment and personnel during maintenance or emergencies.
- Superior Insulation: The D-20 features a double layer of insulation—1" thick fiberboard insulation within the curb, reinforced by 1" thick fiberglass within the cover. This combination provides excellent thermal resistance, helping to maintain consistent temperatures in your building and minimizing energy consumption for heating and cooling.
