Working with architects and construction managers to offer an alternative to cumbersome, fragile, and heavy cast-iron downspout adapters and connectors, Piedmont Manufacturing delivers a lighter, easier-to-use product that's still cost-effective for your project. Our units come standard with mounting hardware, cleanouts, and a durable finish to help them blend seamlessly into your construction. But our downspout connectors are anything but standard with unlimited sizing options and customer products available to suit your project.
A downspout adapter simply connects square or rectangular downspout piping to round piping running away from the building, often referred to as a "roof drain leader." This connection is typically made at or above finished grade. This type of connection requires the use of lightweight downspout running all the way to finished grade and piping next to the building running vertically up to finished grade. With the exception of gum and duct tape (and we've seen both in use), adapters are the lowest-cost connection option.
