48” x 48” - Double Door LightMAX Smoke Vent – Steel & Aluminum  

Trust in BA-BSVLB-D 48” x 48” Double Door LightMAX Smoke Vent – Steel & Aluminum, a state-of-the-art solution that prioritizes your building's and occupant's safety. With an innovative design, this double leaf smoke vent allows a maximum surface area to expel flames, fumes, and gases for unparalleled performance in smoke management, ensuring a safer environment in the event of a fire.  

BA-BSVLB-D's innovative fusible link automatically activates a spring-powered cover for immediate ventilation, and you can count on this model's compression springs to automatically open against wind or loads as high as 10 psf. And with higher-quality insulation, your buildings and your budget will benefit from less consumption. 

Why Invest in BA-BSVLB-D?  

Automated Ventilation: BA-BSVLB-D features a positive releasing latch, activated by a rigorously tested UL-listed fusible link, which melts at temperatures over 165°F. Once the fuse melts, you can count on BA-BSVLB-D's covers to release, expelling flames, fumes, and toxic gases.    

Note: Alternate fusible link temperatures are available; see below.   

Weatherproofed Construction: BA-BSVLB-D has EPDM rubber gaskets permanently adhered to its cover, providing a tight seal while leaving the elements out of your spaces. BA-BSVLB-D has 1" thick PIR insulation within its cover for enhanced thermal resistance (R-6) and reduced energy consumption.    

Note: 2" Polyisocyanurate (PIR) insulation (R-12) is available as an alternative; please contact our staff to request.    

Double-Leaf Design for More Venting Area: BA-BSVLB-D boasts an extra leaf for an expanded area and maximum, crucial ventilation in a fire.   

Glazed Leaf Panel for Natural Lighting: BA-BSVLB-D boasts multiwall white polycarbonate for the added benefit of warming up your spaces with natural light.  

EZ Tab for Easy Mounting: BA-BSVLB-D is a single-wall curb hatch with a mounting flange with EZ tabs that make installations quicker and hassle-free.    

Note: Double wall, curb mount, and double wall with no counterflashing alternatives are available; please contact our staff to request.
