About this asset

Cast iron dome roof drain Revit family featuring a slotted dome strainer seated in a circular clamping ring collar for commercial rainwater drainage. This roof drain assembly consists of a cylindrical lower sump body with vertical reinforcement ribs and an upper clamping flange secured by countersunk perimeter fasteners. Surmounting the base is a rounded dome strainer formed by curved vertical bars that prevent leaves and gravel ballast from clogging the drainage outlet. Fabricated from heavy-duty cast metal with a protective grey coating, the unit exhibits a textured, industrial finish across the bowl and dome cage. The circular aperture and integrated seating lip facilitate installation into flat roof deck build-ups.

The download is a 307 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.

Designed for mechanical and plumbing modelling in Autodesk Revit, this native family loads into project templates to integrate with storm drainage networks. Users can host or position the component at roof slab penetrations, aligning the top rim flush with the roof finish or insulation level. Pipework connectors allow direct routing into vertical rainwater downpipes, streamlining clash detection against structural framing and ceiling plenum services.

Engineered for flat roof systems, this plumbing fixture suits industrial warehouses, commercial office buildings, healthcare facilities, and low-slope residential terraces. Specified during detailed MEP coordination and technical design phases, the unit integrates into gravity storm drainage drawings alongside parapet scuppers and collection sumps.
