- Modular Mix-and-Match Customization: Engineered as a highly adaptable component system, allowing commercial contractors to select and configure parts to meet precise jobsite layout and flat-roof drainage specifications.
- Heavy-Duty Cast Iron & Poly Options: Offers a choice between an ultra-rugged cast iron dome for maximum physical durability and an impact-resistant, UV-stable polyethylene dome for lightweight, corrosion-free performance.
- Watertight Membrane Clamping Ring: Features a heavy-duty cast iron clamping ring designed to exert uniform pressure across the roofing membrane, creating an absolute watertight seal that eliminates roof-surface leakage.
- Structural Underdeck & Sump Support: Pairs a load-distributing sump receiver with a rigid underdeck clamp to solidly stabilize the drain assembly against the roof deck, entirely preventing vertical movement and shifting over time.

Description
The Jay R. Smith 1330 Series Dome and Accessory line is designed for heavy-duty commercial roof drainage applications. Built with cast iron durability, the system includes modular components that ensure watertight performance and adaptability. The 1330D polyethylene dome and 1330CID cast iron dome options provide protection from debris, while the 1330C clamping ring secures the roofing membrane. The 1330UC underdeck clamp reinforces stability beneath the deck, and the 1330SR sump receiver distributes loads and aligns the drain body with the deck opening. This series delivers long-lasting performance for flat roof installations in commercial, industrial, and institutional settings.
