30" x 96" Automatic Smoke Vent - Steel Curb & Aluminum Cover - Bilco

L-40SV 30" x 96" Automatic Smoke Vent – Steel Curb & Aluminum Cover – Bilco  

Protect your building at all costs from getting fire. Install L-40SV Automatic Smoke Vent with durable steel curb that supports the aluminum cover, which automatically opens once the fusible link melts at 165°F (74°C).  

Why Install L-40SV? 

Efficient: The UL-listed fusible link ensures the release of harmful smoke, gasses, heat, and other toxic chemicals in the event of a fire to reduce the risk of people trapped in the building from respiratory illnesses. It also helps them and the fire rescue team to have better visibility.  

Property Protection: The automatic smoke vent reduces the risk of financial loss and property damage due to fire. Reducing the risk of fire or quickly attending to it can also lessen the business' downtime, which allows the company to generate additional income despite the emergency.
