BA-DSH-A optimized by Best Access Doors, features a highly innovative fusible link that automatically activates double-leaf doors for immediate ventilation.

Why Choose BA-DSH-A?
Automatic Double-Leaf Ventilation: BA-DSH-A 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-DSH-A's covers to release, expelling flames, fumes, and toxic gases.
Weatherproofed Construction: BA-DSH-A has EPDM rubber gaskets permanently adhered to its cover, providing a tight seal while leaving the elements out of your spaces. BA-DSH-A's built-in drainage channels leave it highly corrosion-resistant from elemental exposure.
Structural Reinforcement: BA-DSH-A provides live-load support of up to 40 pounds per square foot of load-bearing support to your rooftops.
UL 790 Compliant: BA-DSH-A fortifies your structures with tamper-resistant heavy-gauge steel and a Class A UL 790 rating, providing the highest level of fire resistance for rooftops.
Optimized Energy Efficiency: BA-DSH-A has 1" thick fiberboard insulation within its curb, reinforced by 1"thick fiberglass within its cover for enhanced thermal resistance and reduced energy consumption.
Easier Installations: With a 3-½" mounting flange, an overlapping cover design, and 7/8" predrilled holes, BA-DSH-A easily and securely fastens to roof decks with a straightforward, streamlined process.
