48" x 72" ADC-LV Aluminum Lumivent Daylighting Smoke Vent

A combined fire vent and access hatch is crucial for compliance, as it enables the removal of smoke and heat while providing access to the roof. The 165-degree fusible link in the 48" x 72" ADC-LV Aluminum Lumivent Daylighting Smoke Vent, featuring the Thermolatch II, ensures immediate venting. Its insulated, gasketed aluminum frame guarantees a tight weather seal and easy access.

The ADC-LV is a crucial roof unit designed for automatic smoke and heat ventilation, and safe roof access. It features a Thermolatch II® mechanism that activates when a 165°F fusible link melts, allowing heat and toxic gases to escape.

This outdoor access hatch features a durable 11-gauge aluminum frame and a gasketed design for a weather-tight seal. It includes 1-inch rigid fiberboard insulation and gas springs for smooth manual operation. The translucent polycarbonate glazing allows natural light in, complemented by internal and external pull grips and a hold-open arm for added functionality.
