48" x 48" Smoke Vent Double Leaf Aluminum

BA-ASV-DL Smoke Vent Double Leaf Aluminum  

Best Access Doors' 48" x 48" BA-ASV-DL model is vital to the building's fire, and smoke control system as this access door serves as a smoke vent during fire outbreaks. It also serves as an escape route for people trapped inside and, simultaneously, access for firefighters to get into the building quickly.

Why Must You Install 48" x 48" BA-ASV-DL? 

Installation: The BA-ASV-DL Smoke Vent Double Leaf Aluminum model roof hatch is one of most building contractors' preferred access panels as it is easy to install in the ceiling.  

Accessibility: The BA-ASV-DL self-latching slam latch opens the leaf doors automatically when you push them. It also provides quick access to evacuees and firefighters during fire outbreaks. It also has a 165° UL Listed Fusible Link and a Resettable McCabe link that triggers to open the access door if it detects heavy smoke and fire.   

Durability: The BA-ASV-DL has 11 ga aluminum with a 20 ga aluminum inside liner that can support a live load of 40lbs./sq. Ft. It also has a sealing gasket to provide a flush, tight fit, preventing any water from getting into the building.
