Geberit Manufacturing, Michigan City, Ind., introduces the Terrain™ rapid-draining gutter system. This rainwater system drains water of a speed of up to 1.6 gallons per second. One-piece, hydrodynamic shoulders provide fast, unobstructed water flow from gutter to downspout. Made of PVC-U plastic, the systems will not bend with temperature change, dent when a ladder is placed against them or corrode over time. Strong and lightweight, they require no special tools, machines or manpower to install. Deep elastomeric seals and easy-to-use pivot clips guarantee a watertight seal for years. In addition, the systems are made with colored resins, requiring no maintenance or painting unless desired.
