Industrial Black Cast Iron Dome Roof Drain – RD-100-R

Engineered for flat roof stormwater drainage, this black cast iron dome roof drain Revit family features a slotted strainer and bottom outlet. Cast in heavy-duty dark charcoal iron, the assembly comprises a deep sump bowl, a broad clamping collar ring, and a prominent slotted cage dome strainer fastened by a central vertical bolt. The tapered dome features closely spaced vertical louvres around its perimeter and concentric circular slots across its top surface to catch debris while admitting high-volume rainwater runoff. Below the flange, the cylindrical drain body steps down into a vertical bottom spigot outlet designed for direct connection to vertical leader piping.

The download is a 317 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Load the RFA component directly into your Revit project to coordinate storm drainage runs within MEP and architectural documentation. Position the drain hosted to flat roof slabs, podium decks, or membrane gutters, and align pipe connectors to route downspouts through structural penetrations without clashes. System connector parameters facilitate straightforward piping assignment within gravity drainage networks.

Ideal for commercial developments, industrial warehouses, parking structures, and multi-family residential towers requiring robust rainwater management. The component integrates cleanly into roof detail callouts, plumbing schematics, and coordination models alongside parapet scuppers, roof sumps, and leader pipes. Plumbing engineers and BIM coordinators seeking standard commercial roof drain fixtures will find this asset essential for accurate slab penetrations and stormwater takeoffs across schematic design through construction stages.
