	** NOTE TO SPECIFIER ** Presray Critical Containment Solutions, a division of Pawling Corp.; watertight doors, hatches, and flood barriers. . This section is based on the products of the Presray Critical Containment Solutions, a division of Pawling Corp., which is located at: 32 Nelson Hill Rd P. O. Box 200 Wassaic, NY 12592 Tel: 845-855-1220 Fax: 845-855-8034 Email: info@presray.com www.presray.com . A typical Presray Flood Barrier system consists of a lift-out or hinged barrier with patented inflatable gaskets or compression gaskets on both sides and across the bottom and a conversion frame for connection to the existing door frame. When the gasket is inflated or the compression seal is tightened, the barrier effectively restrains floodwaters, thereby preventing losses to facilities, equipment, and merchandise. Presray Flood Barriers are applicable to both new and existing construction.
