The Ruskin portfolio of life safety solutions includes more than 70 models of 1½-hour rated fire and combination fire/smoke dampers that can be mounted horizontally in UL design I503. The I503 design is a two-hour fire-rated protective membrane made from steel studs and gypsum board. Until recently, UL555 fire dampers were only to be applied in concrete/masonry construction for horizontal applications.
Combined with the flexibility that UL design I503 offers, the Ruskin FSD-LP series provides an energy saving choice for building owners for its airflow performance. In addition, the Ruskin DFD-LP provides installation and maintenance-friendly features.
Ruskin UL-listed solutions are available with a variety of features and options. To learn more, visit the Ruskin website.
