They are engineered specifically to help ensure that outside elements do not penetrate the opening. RJF models are designed for flat roofs with standing water or without cant strips or parapets. RJS models are manufactured for joints on sloped roofs or flat roofs with cant strips. Both models provide excellent resistance to UV rays and moisture deterioration, and they can be anodized to match the building's appearance.   D:\Sites\LocalUser\nystrom\content\0014.htm      © 2005 Nystrom
