About this asset

Industrial cast iron roof drain with side outlet and slotted dome strainer, modeled as a native Revit family for commercial plumbing systems. Engineered for gravity drainage on flat or low-slope decking, this roof drain assembly features a heavy-duty cast iron body with a dark grey industrial finish. A threaded horizontal side outlet projects at ninety degrees from the lower sump, facilitating direct connection into horizontal storm piping within shallow plenum spaces. The upper rim incorporates a secured clamping ring and a hemispherical cast metal dome strainer. Vertically slotted apertures around the strainer prevent gravel and debris intrusion while maintaining unimpeded rainwater intake into the drainage sump.

The download is a 328 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 Autodesk Revit project templates to incorporate into stormwater drainage layouts. Connect piping directly to the threaded side-discharge connector to ensure proper system flow categorization and slope calculation. The compact geometry coordinates accurately in section views, ceiling plenum coordination models, and clash detection routines without generating extraneous polygon overhead.

Suited for commercial, industrial, healthcare, and retail facilities with flat membrane or inverted roof assemblies where structural clearance restricts vertical bottom outlets. Engineers and BIM coordinators routinely place this fixture when detailing rooftop drainage, parapet scuppers, equipment platforms, and canopy downspout takeoffs. Search terminology commonly includes side discharge roof drain, cast iron sump drain, roof strainer, and horizontal storm drain.
