Pipe Portal Systems

A versatile, leak proof and weathertight solution to routing pipes through the roof. The Pipe Portal System is designed to allow for both vertical and horizontal pipe movement, yet provide maintenance free permanent installation, which accommodates pipe sizes of .375" up to 12". The curb cover is molded from ABS plastic (Acrylonitrile Butadiene Styrene) with a laminated acrylic coating, which gives high resistance to both ozone and ultraviolet sun rays, as well as serviceable temperature range of -40F to + 160F. The molded sealing rings on the collared opening of the cover mated with the grooves in the rubber cap assures a "Weather tite Pressure Seal" and mechanical lock.
