The Ruskin portfolio of life safety solutions includes more than 70 models of 1.5-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. The I503 design provides mechanical engineers and contractors with an alternative method of construction for the top or bottom of rated shaft penetrations when applying Ruskin UL dampers. Combined with the flexibility that UL design I503 offers, the Ruskin FSD-LP series provides a cost-effective energy saving choice for building owners. In addition, the Ruskin DFD-LP provides excellent airflow performance along with installation and maintenance-friendly features. Ruskin products are used in commercial applications such as data centers, education facilities, high-rise buildings and healthcare facilities.
