These parts are built for commercial, industrial, and institutional flat-roof drainage systems and are engineered for compatibility with multiple outlet types.

Key Features

• Modular design allows mix-and-match customization for different drainage needs
• Durable cast iron and polyethylene dome options for debris protection
• Clamping ring ensures a watertight membrane seal
• Underdeck clamp and sump receiver provide secure support and load distribution

1010CID – Cast Iron Dome; heavy-duty cast iron construction; protects drain body from debris; high strength for long service life

1010D – Polyethylene Dome; lightweight alternative to cast iron; corrosion-resistant and UV-stable; impact resistant

1010C – Clamping Ring; cast iron construction; secures roofing membrane to drain body; ensures watertight seal

1010UDC – Underdeck Clamp; cast iron or steel; stabilizes drain assembly from below deck; prevents vertical movement

1010SR – Sump Receiver; cast iron construction; distributes load and supports drain body; aligns with roof deck openings

All components compatible with Smith 1010 Series roof drain bodies and outlets

Typical outlet sizes: 2" to 10", with threaded, no-hub, or spigot options depending on body style

• Position sump receiver (1010SR) at deck opening.
• Place roof drain body into receiver and secure with underdeck clamp (1010UDC).
• Align roofing membrane over drain flange.
• Install clamping ring (1010C) to secure membrane and create watertight seal.
• Attach dome strainer — cast iron (1010CID) or polyethylene (1010D) — to complete assembly.
• Verify alignment and water flow. Inspect periodically for debris buildup.

Q: What is the difference between the cast iron dome (1010CID) and the polyethylene dome (1010D)?
A: The cast iron dome provides maximum durability and load resistance, while the polyethylene dome is lightweight, corrosion-resistant, and easier to handle.

Q: What is the purpose of the clamping ring (1010C)?
A: It secures the roofing membrane to the drain body to ensure a watertight seal and prevent leaks.

Q: How does the sump receiver (1010SR) help?
A: It distributes the load of the drain assembly across the roof deck and ensures proper alignment.

Q: Is the underdeck clamp (1010UDC) required?
A: Yes, it stabilizes the drain body from beneath the deck, preventing vertical movement during installation and long-term use.

Q: Are these components compatible with all Jay R. Smith roof drains?
A: They are specifically designed for the Smith 1010 Series, but may be compatible with other Smith drain models depending on configuration.
