Double Pipe Portal Systems

New construction flashings with roof curb mountings

A versatile, leak proof and weathertight solution to routing pipes through the roof.  The Double 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 6".  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 openings of the cover mated with the grooves in the rubber caps assure a "Weather-Tite Pressure Seal" and mechanical lock. 

The protective rubber caps are compression molded of EPDM (Ethylene Propylene Diene Monomer) rubber with a serviceable temperature range of -60F to + 270F, and also have high resistance to both ozone and ultraviolet sun rays.  The conically shaped steps of the cap provide a taut waterproof seal around the pipe and the Stainless Steel Snaplock Swivel Action clamps provided give the added protection to guarantee the pipe seal.  The swivel action of the clamp cuts installation time by 75%.The Double Pipe Portal is ideally used to bring the line sets to condensing units, ice-makers, and chillers etc. Also ideal for mounting roof top satellite dishes.
