Product Summary
A scupper is an opening in the side walls of an open-air structure, for purposes of draining water. They are usually placed at or near ground level, and allow rain or liquids to flow off of the side of the open-air structure, instead of pooling within the walls.

Construction and Materials
The Portals Plus roof drain system is designed for efficient and reliable drainage of flat or low-slope roof surfaces. Its construction prioritizes durability, ease of installation, and effective water management to prevent standing water and potential damage to the roofing system.
Construction Features
- Body: The main body of the roof drain is typically constructed from heavy-duty cast iron, providing robust structural integrity and resistance to corrosion and weathering. This ensures longevity even in harsh environmental conditions.
- Bowl/Receiver: A wide and shallow bowl or receiver is integrated into the drain body. This design facilitates the rapid collection of water from the roof surface and directs it efficiently into the drainage pipe.
- Outlet: The outlet connection is designed for standard plumbing sizes, allowing for easy integration with the building's drainage pipe system.
- Gasket System: A high-quality, durable gasket is incorporated to create a watertight seal between the drain body and the roof membrane, preventing leaks and water ingress into the building structure.
- Gravel Guard/Debris Screen: Many Portals Plus roof drains feature a removable gravel guard or debris screen. This component is crucial for preventing larger debris, leaves, and gravel from entering the drainage system and causing blockages. It is designed for easy removal and cleaning.
- Flange: A wide, integrated flashing flange extends from the drain body, providing ample surface area for secure attachment to the roofing membrane and waterproofing materials. This ensures a continuous and sealed connection.
- Optional Dome: Some models may include an optional debris dome or strainer that sits above the main drain opening. This provides an additional layer of protection against larger debris and can help to elevate collected material away from the drain opening during heavy rainfall.
Materials Used
- Cast Iron: The primary material for the drain body and internal components is high-grade cast iron. This material is chosen for its strength, durability, and resistance to corrosion, making it ideal for outdoor and wet environments.
- Rubber/EPDM: Gaskets and seals are typically made from high-performance rubber compounds, such as EPDM (Ethylene Propylene Diene Monomer). These materials offer excellent flexibility, weather resistance, and long-term sealing capabilities.
- Stainless Steel (Fasteners): Any fasteners used in the assembly or for securing components are often made of stainless steel to prevent rust and corrosion, ensuring the integrity of the drain system over time.
- Plastic (Optional Components): Certain optional components, like some types of debris guards or domes, might be constructed from durable, UV-resistant plastic materials for weight reduction and cost-effectiveness.
