The built-in gutter system is designed to prevent rain and snow from entering the stack. Made from galvanized Spiral pipe for strength and durability; available in most sizes. Weather hoods are pre-assembled for immediate installation. Available with or without Vanstone flange. Click here for basic methods of connecting.
